cargo-semver-checks-action

Lint your crate API changes for semver violations.

- name: Check semver
  uses: obi1kenobi/cargo-semver-checks-action@v2
- name: Publish to crates.io
  run: # your `cargo publish` code here

Input options

Every argument is optional.

Input	Description	Default
package	The package whose API to check for semver (in Package Id Specification format, see https://doc.rust-lang.org/cargo/reference/pkgid-spec.html for reference). If not set, all packages in the workspace are processed.
manifest-path	Path to Cargo.toml of crate or workspace to check.
verbose	Enables verbose output of cargo-semver-checks.	false
github-token	The GITHUB_TOKEN secret used to download precompiled binaries from GitHub API. If not specified, the automatic GitHub token provided to the workflow will be used. The token may be alternatively passed in an environment variable GITHUB_TOKEN.

Use in workspaces with a single crate

The action will work out-of-the-box if it is run inside the package root directory. When the package location is different, you have to specify the path to its Cargo.toml file:

- name: Check semver for my-crate
  uses: obi1kenobi/cargo-semver-checks-action@v2
  with:
    manifest-path: semver/my-crate/Cargo.toml  # or just semver/my-crate/
- name: Publish my-crate to crates.io
  run: # your `cargo publish` code here

Use in workspaces with more than one crate

By default, if workspace contains multiple crates, all of them are checked for semver violations. You can specify a single crate to be checked instead using package or manifest-path.

For example, this will check my-crate:

- name: Check semver for my-crate from the current workspace
  uses: obi1kenobi/cargo-semver-checks-action@v2
  with:
    package: my-crate
- name: Publish my-crate to crates.io
  run: # your `cargo publish` code here

If the action is not run inside the workspace root directory, you again have to specify the path to its Cargo.toml file:

- name: Check semver for all crates from my-workspace
  uses: obi1kenobi/cargo-semver-checks-action@v2
  with:
    manifest-path: semver/my-workspace/Cargo.toml  # or just semver/my-workspace/
- name: Publish my-workspace to crates.io
  run: # your `cargo publish` code here

The two above might be also used together:

- name: Check semver for my-crate from my-workspace
  uses: obi1kenobi/cargo-semver-checks-action@v2
  with:
    manifest-path: semver/my-workspace/Cargo.toml  # or just semver/my-workspace/
    package: my-crate
- name: Publish my-crate to crates.io
  run: # your `cargo publish` code here
