cargo-extern-fn

A cargo subcommand to be used as a pre-processor to various FFI generation libs from a rust crate. Currently support:

cxx: generate cxx::bridge from the public APIs.

Use the /// extern_fn:skip like an attribute to skip items.

Status

This tool is very much a work and progress and it is expected to polish the FFI boundaries by hand afterwards.

Installation

cargo install cargo-extern-fn

Usage

cargo extern-fn --dir [SRC_DIR] && cargo fmt
