Is there a "glibrust" or equivalent standard library for Rust, yet?

Rust of course has a standard library[0] and it includes a libc, but (I might be wrong here) I think the libc portion is FFI into glibc or similar. I think the stuff written in rust is considerably more high-level, focusing more on data structures, concurrency, string manipulation, etc.

We use glibc by default but provide MUSL builds for some platforms as well.

I guess what I'm asking is if the syscall wrappers are in rust or if rust just calls glibc wrappers.

There is the library 'libc' which is a collection of interfaces to (g)libc functions together with the necessary constants and structs [1].

There is the library 'nix-rust' [2], which aims to provide a wrapper of 'libc' in idomatic Rust.

Unlike 'libc', 'nix-rust' does not have a consistent code quality and organization yet. However, Both are missing various bindings for various platforms.

rust relies heavily on libc as far as I know

Some of the standard library does, but the core language does not. (libcore does not, and we've resisted putting libc specific things in core)

No, not heavily. libstd depends on it some (we allow both glibc and musl libcs).

libcore (the baremetal library) and the language don't need libc at all.
