savvy-ffi

Minimal FFI bindings for R's C API. This contains only a subset of APIs sufficient for savvy framework. If you are looking for more complete one, libR-sys is probably what you want.

Some more notable differences between libR-sys are:

• This is NOT a sys crate. Savvy-ffi is intended to be used within an R package, which compiles a staticlib from Rust code first and then links it to R. At the point of compilation by cargo, savvy-ffi is not yet linked, so this is fine.

• All definitions are written by hand, with some help of bindgen, into a single file. There's no automatic version switch or platform switch. If some switch is needed, it will be provided as a feature (e.g. r_4_4_0) and it's user's responsibility to set it properly.
