u32err

This crate implements the core::ops::Try trait with a thin wrapper over u32.

You may use it to implement ergonomic error handling for FFI functions that return non-zero values on failure, or as a lightweight Result.

Example

``rust use u32err::ErrCode; extern "C" { /// This is a function that does something (via FFI). /// /// It returns either a 0 on success, or a non-zero number on failure. /// The real FFI signature of this function returns [u32`], but the types are compatible. fn returnszeroon_success() -> ErrCode; }

fn foo() -> ErrCode { unsafe { returnszeroon_success()?; } ErrCode(0) } ```
