Gary Guo 0f595bab9d rust: build_assert: add build_{error,assert}! macros ... Add the `build_error!` and `build_assert!` macros which leverage the previously introduced `build_error` crate. Do so in a new module, called `build_assert`. The former fails the build if the code path calling it can possibly be executed. The latter asserts that a boolean expression is `true` at compile time. In particular, `build_assert!` can be used in some contexts where `static_assert!` cannot: fn f1<const N: usize>() { static_assert!(N > 1);` // Error. build_assert!(N > 1); // Build-time check. assert!(N > 1); // Run-time check. } #[inline] fn f2(n: usize) { static_assert!(n > 1); // Error. build_assert!(n > 1); // Build-time check. assert!(n > 1); // Run-time check. } Signed-off-by: Gary Guo <gary@garyguo.net> Reviewed-by: Wei Liu <wei.liu@kernel.org> [Reworded, adapted for upstream and applied latest changes] Signed-off-by: Miguel Ojeda <ojeda@kernel.org>		2022-12-04 01:59:16 +01:00
