cffi 0.1.6

Safe* C FFI interface generation

Actions Status Documentation


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.


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.
