nextest-filtering is both an executable binary that can be run, and a library that can be used in Rust programs.
Installing the generate-expr-corpus executable
Assuming you have Rust/Cargo installed, run this command in a terminal:
cargo install nextest-filtering
It will make the generate-expr-corpus command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall nextest-filtering uninstalls.
Adding nextest_filtering library as a dependency
Run this command in a terminal, in your project's directory:
cargo add nextest-filtering
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:
nextest-filtering = "0.18.0"
The nextest_filtering library will be automatically available globally.
Read the nextest_filtering library documentation.
