cffi's Introduction

Actions Status Documentation

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.

cffi's Issues

Use (bytes, len) instead of C strings

It is more versatile to return a struct of (bytes, len) than a null-delimited C string.

The same goes for error callbacks: they should be (bytes, len).
