C-ABI-compatible libc, libm, libpthread, and libunwind interfaces, implemented
in terms of crates written in Rust, such as rsix, origin, sync-resolve,
libm, realpath-ext, memchr, and parking_lot. Currently this only
supports *-*-linux-gnu ABIs, though other ABIs could be added.
The goal is to have very little code in c-scape itself, by factoring out all
of the significant functionality into independent crates with more
Rust-idiomatic APIs, with c-scape just wrapping those APIs to implement the
C ABIs.
This is currently experimental, incomplete, and some things aren't optimized.
c-scape implements malloc using the Rust global allocator, and the default
Rust global allocator is implemented using malloc, so it's necessary to
enable a different global allocator. The [mustang] crate handles this
automatically.
This is part of the Mustang project, building Rust programs written entirely in Rust.
