Rust for Linux Miguel Ojeda Wedson Almeida Filho Alex Gaynor Rust for Linux aims to add Rust support to the Linux kernel. We believe Rust offers key improvements over C in this domain. We hope improvement of Rust for everyone! Introduction Language Library Tooling Nightly features A general priority is to stabilize them (or to find alternatives): https://github.com/Rust-for-Linux/linux/issues/2 0b090148 add w8, w10, w9 Language Memory model: future potential Unified/Compatible Linux kernel and Rust memory models: No need to use inline assembly to define a new memory model.
