All inputs are optional. All inputs are optional.
If a [toolchain file](https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file) (i.e., `rust-toolchain` or `rust-toolchain.toml`) is found in the root of the repository, its `toolchain` value takes precedence. If a [toolchain file](https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file) (i.e., `rust-toolchain` or `rust-toolchain.toml`) is found in the root of the repository and no `toolchain` value is provided, all items specified in the toolchain file will be installed.
If a `toolchain` value is provided, the toolchain file will be ignored.
If no `toolchain` value or toolchain file is present, it will default to `stable`.
First, all items specified in the toolchain file are installed. First, all items specified in the toolchain file are installed.
Afterward, the `components` and `target` specified via inputs are installed in addition to the items from the toolchain file. Afterward, the `components` and `target` specified via inputs are installed in addition to the items from the toolchain file.
