Breaking Changes

This release includes a handful of breaking changes, primarily around TLS backends and the TLS API. For more detail on these changes and how to adapt your code when upgrading from 1.x, please see the migration guide.

  • Isahc now supports choosing between multiple TLS backends, and crate features have been changed to reflect this. Support for rustls as a TLS backend has been added, and the default TLS backend has been changed to be rustls. (#​491)
  • Remove and replace all SSL-related options on Configurable with a new tls module consolidated into tls::TlsConfig. The names of all individual options have been renamed, and include several small breaking changes. (#​491)
    • config::CaCertificate renamed to tls::TrustStore, and expanded with new methods for selecting entire providers of CA certificates, beyond just a single PEM bundle.
    • config::ClientCertificate has been renamed to tls::Identity with additional options for loading certificates and keys from other formats.
    • config::PrivateKey has been moved to tls::PrivateKey.
    • config::SslOption has been removed and merged into regular builder methods for tls::TlsConfig.
  • Redesign NetworkInterface into multiple types in a new net::interface module, which has a more natural API and also supports combining multiple criteria for selecting an interface to bind to. (#​494)
  • Several network-related types have been moved from the config module into the net module. (#​518)
    • config::Dialer and config::DialerParseError moved into net.
    • config::IpVersion moved to net::IpVersion.
    • config::DnCache and config::ResolveMap moved into net::dns.
  • Support for log is now an optional feature, which is enabled by default. (e07e64bd)
Added
  • TLS validation can now be augmented by validating a server's certificate is issued by a specific issuer chain using tls::Issuer. Not all backends support this option. (#​491)
  • Added optional support for using webpki-root-certs as a trust store for root certificates behind a trust-webpki-roots crate feature, which can be used with any TLS backend. This can be used automatically by default combined with rustls by enabling the rustls-tls-webpki-roots crate feature. (#​492)
Changes
  • Add some sanity checks that are performed at runtime when Isahc first initializes to make sure the linked version of libcurl is of a compatible version and seems to be configured to work properly. (#​510)
  • Internal blob handling has been revamped in order to reduce or even eliminate unnecessary copying of in-memory certificates and keys in TLS configuration. This may result in a small performance improvement and reduction in memory usage when using these options. (#​516)
Maintenance
  • Revamp and improve GitHub Actions workflows to test Isahc more comprehensively with more platforms, CPU architectures, and feature combinations. (#​499) (#​500) (#​504)
Dependencies
  • Bump http from 0.2.12 to 1.4.0 (#​472)
  • Bump codecov/codecov-action from 5 to 6 (#​474)

v1.8.2

Compare Source

Dependencies
  • Locked curl-sys to at most 0.4.87 due to a regression in the latest version that causes DNS to hang indefinitely on Windows. See #​501 for more info. (#​507)

v1.8.1

Compare Source

Fixed
  • Fix an agent panic in selector that would sometimes be triggered by multiple socket interests communicated from libcurl for the same socket. Error handling for the agent thread has also been improved in general. (#​460, #​481)
  • Fix a segfault that can occur when the agent thread panics and drops a curl multi handle before its easy handles. This is a bug in the curl-rust project, but we have implemented a workaround that should prevent this from happening for any version of curl-rust you might be using. (#​459, #​461, #​480)
  • Rewrite PSL cache test to not use globals so that they don't randomly fail in CI. (#​485)
  • Improve Debug impl for empty request bodies to distinguish between an empty body and no body.
  • Fix docs.rs failing builds.
Dependency Updates
  • Remove parking lot dependency.
  • Bump psl from 2.1.200 to 2.1.202 (#​484, #​486)

v1.8.0

Compare Source

This is the first maintenance release in a few years and includes a few housekeeping items. No major changes or additions.

Changed
  • Isahc's MSRV has been increased from 1.46.0 to 1.85.0. (#​446)
  • The Public Suffix List Git submodule used for compile-time suffix checking has been removed in favor of the psl crate which provides the same functionality. (#​477)
  • Releases are now managed by release-plz instead of custom workflows.
Dependency Updates
  • Many dependencies have been updated to their latest versions, which should help with compilation in modern environments. Some dependencies now allow for multiple major versions.
  • once_cell has been removed in favor of the equivalent types now provided in std. (#​478)

Breaking changes

  • Referencing keyword-named fields by a raw identifier like {r#type} inside a format string is no longer accepted; simply use the unraw name like {type} (#​347)

    This aligns thiserror with the standard library's formatting macros, which gained support for implicit argument capture later than the release of this feature in thiserror 1.x.

    #[derive(Error, Debug)]
#[error("... {type} ...")]  // Before: {r#type}
pub struct Error {
    pub r#type: Type,
}

  • Trait bounds are no longer inferred on fields whose value is shadowed by an explicit named argument in a format message (#​345)

    // Before: impl<T: Octal> Display for Error<T>
// After: impl<T> Display for Error<T>
#[derive(Error, Debug)]
#[error("{thing:o}", thing = "...")]
pub struct Error<T> {
    thing: T,
}

  • Tuple structs and tuple variants can no longer use numerical {0} {1} access at the same time as supplying extra positional arguments for a format message, as this makes it ambiguous whether the number refers to a tuple field vs a different positional arg (#​354)

    #[derive(Error, Debug)]
#[error("ambiguous: {0} {}", $N)]
//                  ^^^ Not allowed, use #[error("... {0} {n}", n = $N)]
pub struct TupleError(i32);

  • Code containing invocations of thiserror's derive(Error) must now have a direct dependency on the thiserror crate regardless of the error data structure's contents (#​368, #​369, #​370, #​372)

Features

  • Support disabling thiserror's standard library dependency by disabling the default "std" Cargo feature: thiserror = { version = "2", default-features = false } (#​373)

  • Support using r#source as field name to opt out of a field named "source" being treated as an error's Error::source() (#​350)

    #[derive(Error, Debug)]
#[error("{source} ==> {destination}")]
pub struct Error {
    r#source: char,
    destination: char,
}

let error = Error { source: 'S', destination: 'D' };

  • Infinite recursion in a generated Display impl now produces an unconditional_recursion warning (#​359)

    #[derive(Error, Debug)]
#[error("??? {self}")]
pub struct Error;

  • A new attribute #[error(fmt = path::to::myfmt)] can be used to write formatting logic for an enum variant out-of-line (#​367)

    #[derive(Error, Debug)]
pub enum Error {
    #[error(fmt = demo_fmt)]
    Demo { code: u16, message: Option<String> },
}

fn demo_fmt(code: &u16, message: &Option<String>, formatter: &mut fmt::Formatter) -> fmt::Result {
    write!(formatter, "{code}")?;
    if let Some(msg) = message {
        write!(formatter, " - {msg}")?;
    }
    Ok(())
}

  • Enums with an enum-level format message are now able to have individual variants that are transparent to supersede the enum-level message (#​366)

    #[derive(Error, Debug)]
#[error("my error {0}")]
pub enum Error {
    Json(#[from] serde_json::Error),
    Yaml(#[from] serde_yaml::Error),
    #[error(transparent)]
    Other(#[from] anyhow::Error),
}

Major Changes
Surface::get_current_texture now returns CurrentSurfaceTexture enum

Surface::get_current_texture no longer returns Result<SurfaceTexture, SurfaceError>.
Instead, it returns a single CurrentSurfaceTexture enum that represents all possible outcomes as variants.
SurfaceError has been removed, and the suboptimal field on SurfaceTexture has been replaced by a dedicated Suboptimal variant.

match surface.get_current_texture() {
    wgpu::CurrentSurfaceTexture::Success(frame) => { /* render */ }
    wgpu::CurrentSurfaceTexture::Timeout
      | wgpu::CurrentSurfaceTexture::Occluded => { /* skip frame */ }
    wgpu::CurrentSurfaceTexture::Outdated
      | wgpu::CurrentSurfaceTexture::Suboptimal(frame) => { /* reconfigure surface */ }
    wgpu::CurrentSurfaceTexture::Lost => { /* reconfigure surface, or recreate device if device lost */ }
    wgpu::CurrentSurfaceTexture::Validation => {
        /* Only happens if there is a validation error and you
           have registered a error scope or uncaptured error handler. */
    }
}

By @​cwfitzgerald, @​Wumpf, and @​emilk in #​9141 and #​9257.

InstanceDescriptor initialization APIs and display handle changes

A display handle represents a connection to the platform's display server (e.g. a Wayland or X11 connection on Linux). This is distinct from a window — a display handle is the system-level connection through which windows are created and managed.

InstanceDescriptor's convenience constructors (an implementation of Default and the static from_env_or_default method) have been removed. In their place are new static methods that force recognition of whether a display handle is used:

  • new_with_display_handle
  • new_with_display_handle_from_env
  • new_without_display_handle
  • new_without_display_handle_from_env

If you are using winit, this can be populated using EventLoop::owned_display_handle.

- InstanceDescriptor::default();
- InstanceDescriptor::from_env_or_default();
+ InstanceDescriptor::new_with_display_handle(Box::new(event_loop.owned_display_handle()));
+ InstanceDescriptor::new_with_display_handle_from_env(Box::new(event_loop.owned_display_handle()));

Additionally, DisplayHandle is now optional when creating a surface if a display handle was already passed to InstanceDescriptor. This means that once you've provided the display handle at instance creation time, you no longer need to pass it again for each surface you create.

By @​MarijnS95 in #​8782

Bind group layouts now optional in PipelineLayoutDescriptor

This allows gaps in bind group layouts and adds full support for unbinding, bring us in compliance with the WebGPU spec. As a result of this PipelineLayoutDescriptor's bind_group_layouts field now has type of &[Option<&BindGroupLayout>]. To migrate wrap bind group layout references in Some:

  let pl_desc = wgpu::PipelineLayoutDescriptor {
      label: None,
      bind_group_layouts: &[
-         &bind_group_layout
+         Some(&bind_group_layout)
      ],
      immediate_size: 0,
  });

By @​teoxoy in #​9034.

MSRV update

wgpu now has a new MSRV policy. This release has an MSRV of 1.87. This is lower than v27's 1.88 and v28's 1.92. Going forward, we will only bump wgpu's MSRV if it has tangible benefits for the code, and we will never bump to an MSRV higher than stable - 3. So if stable is at 1.97 and 1.94 brought benefit to our code, we could bump it no higher than 1.94. As before, MSRV bumps will always be breaking changes.

By @​cwfitzgerald in #​8999.

WriteOnly

To ensure memory safety when accessing mapped GPU memory, MapMode::Write buffer mappings (BufferViewMut and also QueueWriteBufferView) can no longer be dereferenced to Rust &mut [u8]. Instead, they must be used through the new pointer type wgpu::WriteOnly<[u8]>, which does not allow reading at all.

WriteOnly<[u8]> is designed to offer similar functionality to &mut [u8] and have almost no performance overhead, but you will probably need to make some changes for anything more complicated than get_mapped_range_mut().copy_from_slice(my_data); in particular, replacing view[start..end] with view.slice(start..end).

By @​kpreid in #​9042.

Depth/stencil state changes

The depth_write_enabled and depth_compare members of DepthStencilState are now optional, and may be omitted when they do not apply, to match WebGPU.

depth_write_enabled is applicable, and must be Some, if format has a depth aspect, i.e., is a depth or depth/stencil format. Otherwise, a value of None best reflects that it does not apply, although Some(false) is also accepted.

depth_compare is applicable, and must be Some, if depth_write_enabled is Some(true), or if depth_fail_op for either stencil face is not Keep. Otherwise, a value of None best reflects that it does not apply, although Some(CompareFunction::Always) is also accepted.

There is also a new constructor DepthStencilState::stencil which may be used instead of a struct literal for stencil operations.

Example 1: A configuration that does a depth test and writes updated values:

 depth_stencil: Some(wgpu::DepthStencilState {
     format: wgpu::TextureFormat::Depth32Float,
-    depth_write_enabled: true,
-    depth_compare: wgpu::CompareFunction::Less,
+    depth_write_enabled: Some(true),
+    depth_compare: Some(wgpu::CompareFunction::Less),
     stencil: wgpu::StencilState::default(),
     bias: wgpu::DepthBiasState::default(),
 }),

Example 2: A configuration with only stencil:

 depth_stencil: Some(wgpu::DepthStencilState {
     format: wgpu::TextureFormat::Stencil8,
-    depth_write_enabled: false,
-    depth_compare: wgpu::CompareFunction::Always,
+    depth_write_enabled: None,
+    depth_compare: None,
     stencil: wgpu::StencilState::default(),
     bias: wgpu::DepthBiasState::default(),
 }),

Example 3: The previous example written using the new stencil() constructor:

depth_stencil: Some(wgpu::DepthStencilState::stencil(
    wgpu::TextureFormat::Stencil8,
    wgpu::StencilState::default(),
)),
D3D12 Agility SDK support

Added support for loading a specific DirectX 12 Agility SDK runtime via the Independent Devices API. The Agility SDK lets applications ship a newer D3D12 runtime alongside their binary, unlocking the latest D3D12 features without waiting for an OS update.

Configure it programmatically:

let options = wgpu::Dx12BackendOptions {
    agility_sdk: Some(wgpu::Dx12AgilitySDK {
        sdk_version: 619,
        sdk_path: "path/to/sdk/bin/x64".into(),
    }),
    ..Default::default()
};

Or via environment variables:

WGPU_DX12_AGILITY_SDK_PATH=path/to/sdk/bin/x64
WGPU_DX12_AGILITY_SDK_VERSION=619

The sdk_version must match the version of the D3D12Core.dll in the provided path exactly, or loading will fail.

If the Agility SDK fails to load (e.g. version mismatch, missing DLL, or unsupported OS), wgpu logs a warning and falls back to the system D3D12 runtime.

By @​cwfitzgerald in #​9130.

primitive_index is now a WGSL enable extension

WGSL shaders using @builtin(primitive_index) must now request it with enable primitive_index;. The SHADER_PRIMITIVE_INDEX feature has been renamed to PRIMITIVE_INDEX and moved from FeaturesWGPU to FeaturesWebGPU. By @​inner-daemons in #​8879 and @​andyleiserson in #​9101.

- device.features().contains(wgpu::FeaturesWGPU::SHADER_PRIMITIVE_INDEX)
+ device.features().contains(wgpu::FeaturesWebGPU::PRIMITIVE_INDEX)
// WGSL shaders must now include this directive:
enable primitive_index;
maxInterStageShaderComponents replaced by maxInterStageShaderVariables

Migrated from the max_inter_stage_shader_components limit to max_inter_stage_shader_variables, following the latest WebGPU spec. Components counted individual scalars (e.g. a vec4 = 4 components), while variables counts locations (e.g. a vec4 = 1 variable). This changes validation in a way that should not affect most programs. By @​ErichDonGubler in #​8652, #​8792.

  • GPUFeatureName now includes all wgpu extensions. Feature names for extensions should be written with a wgpu- prefix, although unprefixed names that were accepted previously are still accepted. By @​andyleiserson in #​9163.

Bug Fixes
General
  • Tracing support has been restored. By @​andyleiserson in #​8429.
  • Pipelines using passthrough shaders now correctly require explicit pipeline layout. By @​inner-daemons in #​8881.
  • Allow using a shader that defines I/O for dual-source blending in a pipeline that does not make use of it. By @​andyleiserson in #​8856.
  • Improve validation of dual-source blending, by @​andyleiserson in #​9200:
    • Validate structs with @blend_src members whether or not they are used by an entry point.
    • Dual-source blending is not supported when there are multiple color attachments.
    • TypeFlags::IO_SHAREABLE is not set for structs other than @blend_src structs.
  • Validate strip_index_format isn't None and equals index buffer format for indexed drawing with strip topology. By @​beicause in #​8850.
  • BREAKING: Renamed EXPERIMENTAL_PASSTHROUGH_SHADERS to PASSTHROUGH_SHADERS and made this no longer an experimental feature. By @​inner-daemons in #​9054.
  • BREAKING: End offsets in trace and player commands are now represented using offset + size instead. By @​ErichDonGubler in #​9073.
  • Validate some uncaught cases where buffer transfer operations could overflow when computing an end offset. By @​ErichDonGubler in #​9073.
  • Fix local_invocation_id and local_invocation_index being written multiple times in HLSL/MSL backends, and naming conflicts when users name variables __local_invocation_id or __local_invocation_index. By @​inner-daemons in #​9099.
  • Added internal labels to validation GPU objects and timestamp normalization code to improve clarity in graphics debuggers. By @​szostid in #​9094
  • Fix multi-planar texture copying. By @​noituri in #​9069
naga
  • The validator checks that override-sized arrays have a positive size, if overrides have been resolved. By @​andyleiserson in #​8822.
  • Fix some cases where f16 constants were not working. By @​andyleiserson in #​8816.
  • Use wrapping arithmetic when evaluating constant expressions involving u32. By @​andyleiserson in #​8912.
  • Fix missing side effects from sequence expressions in GLSL. By @​Vipitis in #​8787.
  • Naga now enforces the @must_use attribute on WGSL built-in functions, when applicable. You can waive the error with a phony assignment, e.g., _ = subgroupElect(). By @​andyleiserson in #​8713.
  • Reject zero-value construction of a runtime-sized array with a validation error. Previously it would crash in the HLSL backend. By @​mooori in #​8741.
  • Reject splat vector construction if the argument type does not match the type of the vector's scalar. Previously it would succeed. By @​mooori in #​8829.
  • Fixed workgroupUniformLoad incorrectly returning an atomic when called on an atomic, it now returns the inner T as per the spec. By @​cryvosh in #​8791.
  • Fixed constant evaluation for sign() builtin to return zero when the argument is zero. By @​mandryskowski in #​8942.
  • Allow array generation to compile with the macOS 10.12 Metal compiler. By @​madsmtm in #​8953
  • Naga now detects bitwise shifts by a constant exceeding the operand bit width at compile time, and disallows scalar-by-vector and vector-by-scalar shifts in constant evaluation. By @​andyleiserson in #​8907.
  • Naga uses wrapping arithmetic when evaluating dot products on concrete integer types (u32 and i32). By @​BKDaugherty in #​9142.
  • Disallow negation of a matrix in WGSL. By @​andyleiserson in #​9157.
  • Fix evaluation order of compound assignment (e.g. +=) LHS and RHS. By @​andyleiserson in #​9181.
  • Fixed invalid MSL when float16-format vertex input data was accessed via an f16-type variable in a vertex shader. By @​andyleiserson in #​9166.
Validation
  • Fixed validation of the texture format in GPUDepthStencilState when neither depth nor stencil is actually enabled. By @​andyleiserson in #​8766.
  • Check that depth bias is not used with non-triangle topologies. By @​andyleiserson in #​8856.
  • Check that if the shader outputs frag_depth, then the pipeline must have a depth attachment. By @​andyleiserson in #​8856.
  • Fix incorrect acceptance of some swizzle selectors that are not valid for their operand, e.g. const v = vec2<i32>(); let r = v.xyz. By @​andyleiserson in #​8949.
  • Fixed calculation of the total number of bindings in a pipeline layout when validating against device limits. By @​andyleiserson in #​8997.
  • Reject non-constructible types (runtime- and override-sized arrays, and structs containing non-constructible types) in more places where they should not be allowed. By [@​a
