linux.git/rust/macros/zeroable.rs, branch v6.6.132 Clone of https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git rust: add derive macro for `Zeroable` 2023-08-21T12:31:48+00:00 Benno Lossin benno.lossin@proton.me 2023-08-14T08:46:41+00:00 071cedc84e907f6984b3de3285ec2b077d3c3cdb Add a derive proc-macro for the `Zeroable` trait. The macro supports structs where every field implements the `Zeroable` trait. This way `unsafe` implementations can be avoided. The macro is split into two parts: - a proc-macro to parse generics into impl and ty generics, - a declarative macro that expands to the impl block.

Add a derive proc-macro for the `Zeroable` trait. The macro supports
structs where every field implements the `Zeroable` trait. This way
`unsafe` implementations can be avoided.

The macro is split into two parts:
- a proc-macro to parse generics into impl and ty generics,
- a declarative macro that expands to the impl block.
