Rust — The Mesa 3D Graphics Library latest documentation

# Rust

## Rust Subproject Names

All Rust subprojects should follow the convention `NAME-SEMVER-rs`, where `SEMVER` is the version up to and including the first nonzero component. For example, `zerocopy-0.8.13` becomes `zerocopy-0.8-rs`, whereas `syn-2.0.66` becomes `syn-2-rs`.

## Rust Update Policy

Given that for some distributions it’s not feasible to keep up with the pace of Rust, we promise to only bump the minimum required Rust version following those rules:

- Only up to the Rust requirement of other major Linux desktop components, e.g.:

  - Firefox ESR: Minimum Supported Rust Version:

  - latest Linux Kernel Rust requirement

- Only require a newer Rust version than stated by other rules if and only if it’s required to get around a bug inside rustc.

As bug fixes might run into rustc compiler bugs, a rust version bump _can_ happen on a stable branch as well.

## Peripheral Support for crates.io uploads

Certain Mesa crates are uploaded to crates.io at the discretion of certain sub-communities of Mesa. These crates are:

- https://crates.io/crates/magma-gpu

These crates are used as dependencies to other Rust-based projects, such as:

- https://crates.io/crates/rutabaga_gfx

This is not supported by the “core” Mesa quarterly release cycles, and the official Mesa maintainers are not liable for use or mis-use of the crates. Please contact the relevant sub-community before using these crates outside of Mesa3D.

Official Mesa distribution of crates will likely have wait until improvements are made in the Meson build system:

- https://github.com/mesonbuild/meson/issues/2173

The Meson build system is the only build system officially supported by Mesa3D.
