unsafe-ffi

The unsafe-ffi tag on WindowsForum.com covers discussions about the use of Rust's unsafe foreign function interface (FFI) in Windows driver development. Recent content highlights Microsoft's efforts to integrate Rust as a first-class language for Windows drivers, leveraging unsafe-ffi to interface with existing C/C++ code and hardware. Topics include the windows-drivers-rs crate platform, cargo-wdk tooling, and the balance between Rust's memory safety guarantees and the necessity of unsafe blocks for low-level operations. The tag is relevant for developers working on kernel-mode or user-mode drivers who need to understand how Rust's unsafe-ffi interacts with the Windows Driver Kit (WDK) and legacy codebases.
