cargo-feature-combinations
Plugin for cargo
to run commands against selected combinations of features.
Installation
cargo install cargo-feature-combinations
Usage
In most cases, just use the command as if it was cargo
.
However, there are a few optional flags and the matrix
subcommand.
cargo feature-combinations check
To save time, you can also use the shortened name cargo fc
:
cargo fc test
cargo fc --fail-fast test
cargo fc build
cargo fc --silent build
cargo fc matrix
For details, please refer to --help
:
$ cargo fc --help
USAGE:
cargo [+toolchain] [SUBCOMMAND] [SUBCOMMAND_OPTIONS]
cargo [+toolchain] [OPTIONS] [CARGO_OPTIONS] [CARGO_SUBCOMMAND]
SUBCOMMAND:
matrix Print JSON feature combination matrix to stdout
--pretty Print pretty JSON
OPTIONS:
--help Print help information
--silent Hide cargo output and only show summary
--fail-fast Fail fast on the first bad feature combination
--errors-only Allow all warnings, show errors only (-Awarnings)
--pedantic Treat warnings like errors in summary and
when using --fail-fast
Configuration
In your Cargo.toml
, you can configure the feature combination matrix:
[package.metadata.cargo-feature-combinations]
# Exclude groupings of features that are incompatible or do not make sense
skip_feature_sets = [ ["foo", "bar"], ]
# Exclude features from the feature combination matrix
denylist = ["default", "full"]
Usage with github-actions
The github-actions matrix feature allows more efficient testing of all feature set combinations in CI.
The following workflow file uses cargo-feature-combinations
to automatically generate a feature matrix and runs up to 256 feature combinations in a matrix job.
# TODO: embed example
Local development
For local development and testing, you can point cargo fc
to another project using
the --manifest-path
flag.
cargo run -- cargo check --manifest-path ../path/to/Cargo.toml
cargo run -- cargo matrix --manifest-path ../path/to/Cargo.toml --pretty
Linting
cargo clippy --tests --benches --examples -- -Dclippy::all -Dclippy::pedantic
Acknowledgements
The cargo-all-features
crate is similar yet offers more complex configuration and is lacking a summary.
TODO
- allow adding custom data to matrix output
- embed the help output using embedme.
- add a github actions workflow file example.
