WebProvides macros to support bitfield structs allowing for modular use of bit-enums. The mainly provided macros are #[bitfield] for structs and #[derive(BitfieldSpecifier)] for enums that shall be usable within bitfield structs.. There are preset bitfield specifiers such as B1, B2,..,B64 that allow for easy bitfield usage in structs very similar to how they work in C … WebJan 27, 2024 · The goal of C2Rust is to translate any standard C code into Rust. To translate bitfields from C, we therefore require drop-in compatible bitfield support. Since the Rust ecosystem revolves around sharing code in libraries (called crates), we decided to look at the few most promising crates to see what was available. inbound and outbound travel meaning
