Action seems to ignore rust-toolchain files

• You've read the Contributing section about bugs reporting: https://github.com/actions-rs/.github/blob/master/CONTRIBUTING.md#reporting-bugs
• Is this something you can debug and fix? Send a pull request! Bug fixes and documentation fixes are welcome.

Description

It does not seem that rust-toolchain files are read.

Workflow code

https://github.com/jack-signal/gh-actions-test/blob/5666895d3ee0ca51506901b09d6d94a8758e8e9a/.github/workflows/rust.yml

Relevant part

    - name: Install nightly rust
      uses: actions-rs/toolchain@v1
      with:
        profile: minimal
        components: rustfmt, clippy

Action output

Expected behavior

The problem here is - the repository does have a rust-toolchain file in the root directory, so I would expect that it would be used.

Hi, @jack-signal! You still need to check out your code first, otherwise there are no files at all at the working directory.

Please, see actions/checkout@v2 line at the example workflow and to GH Actions documentation

Oh my gosh I can't believe I missed that, thank you.
