mustang VS rustix

It would be great for Rust to have a Linux target that doesn't use libc, but from what I've read, not many people are interested in this.

On Linux there has been some attempts to get exactly this solutions, most notibly https://github.com/sunfishcode/mustang but the topic did not seem to fetch a prominent position on the supported feature list.

For Linux, Mustang already exists because Linux has a stable syscall API

Why bother with a libc at all, when you can skip it entirely on Linux!

Mustang is a project which is able to run some non-trivial programs written in Rust, such as ripgrep, without using any libc, on Linux.

Mustang is one way to take care of the tiny amount of "C" that runs before main().

This is more a Rust question than a Zig question. In Rust, the choice of a specific libc (or to not use a libc) is part of the "target", for example many hardware platforms have gnu/musl/none targets. See also relibc or mustang for pure-rust alternatives. Each libc alternative require some work to integrate into Rust.

There's a separate project for that, called Mustang. It's built on top of rustix and provides all those things. It's not super mature yet, but it is able to run ripgrep by itself: https://github.com/sunfishcode/mustang

Without actually having looked into this, how does https://github.com/bytecodealliance/rustix fit into points 1 & 2?

I find this github issue: https://github.com/bytecodealliance/rustix/issues/575

Hi Rust experts, we are willing to integrate rustix on NuttX RTOS, the initial effort was done by rustix author: https://github.com/bytecodealliance/rustix/tree/nuttx but it hit the wall since we don't know the right way to integrate cargo with the old-school NuttX's Makefiles. Any help or suggestion is welcome. More about NuttX here: https://nuttx.apache.org and here: https://nuttx.apache.org/docs/latest/

Have you considered using rustix? It provides many of the facilities of std without using libc.

rustix can make syscalls directly to Linux. There's a rustc fork that can use it to build std.

The rustix project claims to use raw syscalls (and vDSO calls) on linux and provides more memory / type safety compared to the libc API.

Hi, the reason is explained by the description of https://github.com/bytecodealliance/rustix.

Please consider rustix as an alternative to nix.
