# Install Rust Toolchain
|
||
|
|
|
||
|
|
This GitHub Action installs a Rust toolchain using rustup.
|
||
|
|
It further integrates into the ecosystem.
|
||
|
|
Caching for Rust tools and build artifacts is enabled.
|
||
|
|
Environment variables are set to optimize the cache hits.
|
||
|
|
[Problem Matchers] are provided for build messages (cargo, clippy) and formatting (rustfmt).
|
||
|
|
|
||
|
|
The action is heavily inspired by *dtolnay*'s <https://github.com/dtolnay/rust-toolchain> and extends it with further features.
|
||
|
|
|
||
|
|
