rust-components-nightly Action

This GitHub Action finds the latest Rust nightly build with the requested component available.

Deprecation notice

Since actions-rs/toolchain Action is now utilizes rustup ability to find the most recent nightly build with multiple components available, this Action is deprecated now.
Consider removing it from your workflows and use actions-rs/toolchain directly.

For example, instead of

steps:
  - uses: actions/checkout@master
  - id: component
    uses: actions-rs/components-nightly@v1
    with:
      component: clippy
  - uses: actions-rs/toolchain@v1
    with:
        toolchain: ${{ steps.component.outputs.toolchain }}
        override: true

you can now tune actions-rs/toolchain action:

steps:
  - uses: actions/checkout@master
  - uses: actions-rs/toolchain@v1
    with:
        toolchain: nightly
        components: clippy
        override: true

See Components section for more.

This Action will not be updated anymore, but will be leaved as is in order not to break workflows, which are using it already.

Background

Ever had the problem when your nightly build breaks because today nightly does not has the clippy available? With this Action you can find the most recent nightly build with the clippy available.

Found toolchain name will be set as an Action output, ex. nightly-2019-09-13-x86_64-unknown-linux-gnu.

Note that this Action does not do anything else with the found toolchain, you need to install it / set as an override manually, for example, with a actions-rs/toolchain Action.

Example workflow

on: [push]

name: nightly clippy

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      - id: component
        uses: actions-rs/components-nightly@v1
        with:
          component: clippy
      - uses: actions-rs/toolchain@v1
        with:
            toolchain: ${{ steps.component.outputs.toolchain }}
            override: true
