What does this PR try to resolve?
The documentation for the unstable
build-std-featuresflag mentions that a default-enabled feature forstdispanic_unwind. However, as of 2023-07-16, that feature does not even exist in the latest nightlies:The
stdCargo.tomldoes not contain thepanic_unwindfeature either, but it defines apanic-unwindfeature, which works as intended with thebuild-std-featuresflag.Therefore, let's update the documentation to refer to the intended feature instead, which improves its accuracy and reduces developer time waste.
How should we test and review this PR?
Run e.g.
cargo build --release -Z build-std -Z build-std-features=panic-unwind --target x86_64-unknown-linux-gnuinstead ofcargo build --release -Z build-std -Z build-std-features=panic_unwind --target x86_64-unknown-linux-gnu, and watch how the first one works as intended but the second one just shows an error.
