c-gull
A libc implementation in Rust
c-gull is a libc implementation. It is an implementation of the ABI described by the libc crate.
It is implemented in terms of crates written in Rust, such as c-scape, rustix, origin, sync-resolve, libm, realpath-ext, tz-rs, printf-compat, and rand.
Currently it only supports *-*-linux-gnu ABIs, though other ABIs could be
added in the future. And currently this mostly focused on features needed by
Rust programs, so it doesn’t have many C-idiomatic things like printf yet, but
they could be added in the future.
The goal is to have very little code in c-gull itself, by factoring out all of the significant functionality into independent crates with more Rust-idiomatic APIs, with c-gull just wrapping those APIs to implement the C ABIs.
This is currently highly experimental, incomplete, and some things aren’t optimized.
This is part of the Mustang project, building Rust programs written entirely in Rust.
Using c-gull in non-mustang programs
c-gull can also be used as a drop-in (partial) libc replacement in non-mustang builds, provided you’re using nightly Rust. To use it, just change your typical libc dependency in Cargo.toml to this:
libc = { version = "<c-gull version>", package = "c-gull" }and c-gull will replace as many of the system libc implementation with its own
implementations as it can. In particular, it can’t replace malloc or any of
the pthread functions in this configuration, but it can replace many other
things.
See the libc-replacement example for more details.
