cffi-rs/cffi

Safe* C foreign function interface for Rust, using proc macros and marshaling types.

cffi

Use the #[cffi::marshal(...)] proc macro to make unsafe C functions into much safer functions, both for exporting interfaces and consuming functions from C libraries.

Usage

See the documentation for the various marshallers available.

Where is this used?

• pahkat - a multi-platform package management framework
• divvunspell - a multi-platform highly efficient memory-mapping spell checking library

Background and philosophy

We enforce the usage of stdint.h types on the C side to simplify the implementation on the Rust side.
