## What it is
safer_ffi is a Rust framework for writing foreign function interfaces without polluting code with unsafe blocks. It provides attribute macros to export Rust functions and types to C, including automatic C header generation.

## Use cases
- expose rust functions to c callers
- generate c headers from rust code
- write ffi bindings without unsafe code
- build a c-compatible static or dynamic library from rust
- call rust code from c or other languages

## When to choose
- you maintain a rust library consumed from c, c++, or other ffi-capable languages
- you want safe, readable ffi signatures instead of raw pointers
- you need automatic c header generation

## When to avoid
- you need bindings between two non-rust languages
- you need stable, fully mature guarantees - it is still in an alpha/rc stage
- your project is pure rust with no ffi boundary

## Facets
- artifact type: library
- maturity: active
- function: sdk, developer-tools, parser
- domain: developer-tools, programming-languages, cross-platform
- platform: rust, cpp, c, cross-platform
- tags: ffi, bindings, c-interop, header-generation, no-std, unsafe-rust
