Compatibility Notes ------------------- - [Introduce `pin_v2` into the builtin attributes namespace] (rust-lang/rust#139751) - [Update bundled musl to 1.2.5] (rust-lang/rust#142682) - [On Emscripten, the unwinding ABI used when compiling with `panic=unwind` was changed from the JS exception handling ABI to the wasm exception handling ABI.] (rust-lang/rust#147224) If linking C/C++ object files with Rust objects, `-fwasm-exceptions` must be passed to the linker now. On nightly Rust, it is possible to get the old behavior with `-Zwasm-emscripten-eh=false -Zbuild-std`, but it will be removed in a future release. - The `#[test]` attribute, used to define tests, was previously ignored in various places where it had no meaning (e.g on trait methods or types). Putting the `#[test]` attribute in these places is no longer ignored, and will now result in an error; this may also result in errors when generating rustdoc. [Error when `test` attribute is applied to structs] (rust-lang/rust#147841) - Cargo now sets the `CARGO_CFG_DEBUG_ASSERTIONS` environment variable in more situations. This will cause crates depending on `static-init` versions 1.0.1 to 1.0.3 to fail compilation with "failed to resolve: use of unresolved module or unlinked crate `parking_lot`". See [the linked issue] (rust-lang/rust#150646 (comment)) for details. - [User written types in the `offset_of!` macro are now checked to be well formed.] (rust-lang/rust#150465) - `cargo publish` no longer emits `.crate` files as a final artifact for user access when the `build.build-dir` config is unset

How to test and review this PR?
As for testing, I was unsure if it was worth exhaustively testing every variant of every format option
