Tiny std

Like a bad, probably buggy, tiny standard library for Linux.

NOTICE: Broken v0.1.0 on stable >= 1.72 / nightly >= 08-17

Some update to rustc between 2023-08-16 and 2023-08-17 caused miscompilations of tiny-std resulting in infinite recursion on calls to memset, which the compiler inserts sometimes as part of optimization a bit more details here.
This was fixed in v0.1.1 with no API-changes by breaking code sensitive to rewrites into a separate crate with a #![no_builtins].

Therefore, version 0.1.0 was yanked from crates.io.

When it's appropriate

If you are actually trying to do something solid, checkout Rustix or Relibc.

The regular stdlib is probably going to be better for almost all use-cases, since the only supported os is Linux you likely have an allocator present, although tiny-std will in my testing at least, produce a much smaller binary.

Supported platforms

  1. x86_64
  2. aarch64

Core features

  1. Run with or without alloc
  2. Minimal fs coverage
  3. Minimal spawn coverage
  4. Minimal unix socket support
  5. Minimal threading support
  6. Experimental io_uring support

Wanted features (in no particular order)

  1. Signal handling by signalfd
  2. Threading would be nice, but reinventing that particular wheel will likely explode code footprint and be hard to get right.
  3. io-uring fs operations

Examples

  • PGWM is the biggest project built with tiny-std.
    At present, the minimal WM builds statically pie-linked at 790K.
  • Some examples of working setups for binary projects are in test-runners, both with and without an allocator/threading.
