st0x-pricing-types

Wire types for the st0x.pricing service and its consumers (st0x.bebop, st0x.hook, st0x-oracle-server).

Pure Rust, no Foundry, no submodules. The crate is the schema; the struct definitions are the contract.

Use

[dependencies]
st0x-pricing-types = { git = "https://github.com/ST0x-Technology/st0x.pricing-types", tag = "v0.2.0" }

use st0x_pricing_types::{ClientFrame, ServerFrame, WireFloat};

let frame: ServerFrame = ciborium::from_reader(&bytes[..])?;

Converting to rain_math_float::Float

This crate intentionally does not depend on rain-math-float — that crate's sol! macros need Foundry's forge build at compile time, and a bytes-only consumer shouldn't have to pay that. Consumers that need Float arithmetic do the conversion themselves:

use alloy::primitives::B256;
use rain_math_float::Float;
use st0x_pricing_types::WireFloat;

let f = Float::from_raw(B256::from(wire.0));
let display = f.format()?;
