2025-01-10rust: add `build_error!` to the preludeMiguel Ojeda
The sibling `build_assert!` is already in the prelude, it makes sense that a "core"/"language" facility like this is part of the prelude and users should not be defining their own one (thus there should be no risk of future name collisions and we would want to be aware of them anyway). Thus add `build_error!` into the prelude.

2025-01-10rust: use the `build_error!` macro, not the hidden functionMiguel Ojeda
Code and some examples were using the function, rather than the macro. The macro is what is documented. Thus move users to the macro.

2024-11-10rust: use custom FFI integer typesGary Guo
Currently FFI integer types are defined in libcore. This commit creates the `ffi` crate and asks bindgen to use that crate for FFI integer types instead of `core::ffi`. This commit is preparatory and no type changes are made in this commit yet. Signed-off-by: Gary Guo <gary@garyguo.net> Link: https://lore.kernel.org/r/20240913213041.395655-4-gary@garyguo.net [ Added `rustdoc`, `rusttest` and KUnit tests support. Rebased on top of `rust-next` (e.g. migrated more `core::ffi` cases). Reworded crate docs slightly and formatted. - Miguel ] Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
