       "description": "The `panic` setting controls the [`-C panic` flag](https://doc.rust-lang.org/rustc/codegen-options/index.html#panic) which controls which panic\nstrategy to use.\n\nWhen set to `\"unwind\"`, the actual value depends on the default of the target\nplatform. For example, the NVPTX platform does not support unwinding, so it\nalways uses `\"abort\"`.\n\nTests, benchmarks, build scripts, and proc macros ignore the `panic` setting.\nThe `rustc` test harness currently requires `unwind` behavior. See the\n[`panic-abort-tests`](https://doc.rust-lang.org/cargo/reference/unstable.html#panic-abort-tests) unstable flag which enables `abort` behavior.\n\nAdditionally, when using the `abort` strategy and building a test, all of the\ndependencies will also be forced to built with the `unwind` strategy.",
