## Example workflow
```yaml
on: [push]
name: CI
jobs:
build_and_test:
name: Rust project
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- uses: actions-rs/cargo@v1
with:
command: build
args: --release --all-features
```
See [additional recipes here](https://github.com/actions-rs/meta).
## 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`](https://github.com/rust-embedded/cross) instead of `cargo` | bool | false |
## Toolchain
By default this Action will call whatever `cargo` binary is available
in the current [virtual environment](https://help.github.com/en/articles/software-in-virtual-environments-for-github-actions).
You can use [`actions-rs/toolchain`](https://github.com/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](https://github.com/rust-embedded/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.
```yaml
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
```
