Example workflow

on: [push]

name: CI

jobs:
  build_and_test:
    name: Rust project
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions-rs/toolchain@v1
        with:
          toolchain: stable
      - uses: actions-rs/cargo@v1
        with:
          command: build
          args: --release --all-features

See additional recipes here.

Use cases

Note that this Action is not required usually and you can just use run step instead as in example below:

jobs:
  build_and_test:
    name: Rust project
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions-rs/toolchain@v1
        with:
          toolchain: stable
      - run: cargo build --release --all-features

Why would you want to use this Action instead:

1. Transparent cross installation and execution with use-cross: true input enabled
2. Warnings and errors issued by cargo will be displayed in GitHub UI

Inputs

Name	Required	Description	Type	Default
command	✓	Cargo command to run, ex. check or build	string
toolchain		Rust toolchain name to use	string
args		Arguments for the cargo command	string
use-cross		Use cross instead of cargo	bool	false

Toolchain

By default this Action will call whatever cargo binary is available in the current virtual environment.

You can use actions-rs/toolchain to install specific Rust toolchain with cargo included.

Cross-compilation

In order to make cross-compile an easy process, this Action can install cross tool on demand if use-cross input is enabled; cross executable will be invoked then instead of cargo automatically.

All consequent calls of this Action in the same job with use-cross: true input enabled will use the same cross installed.

on: [push]

name: ARMv7 build

jobs:
  linux_arm7:
    name: Linux ARMv7
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions-rs/toolchain@v1
        with:
          toolchain: stable
          target: armv7-unknown-linux-gnueabihf
          override: true
      - uses: actions-rs/cargo@v1
        with:
          use-cross: true
          command: build
          args: --target armv7-unknown-linux-gnueabihf
