Required Methods§

Source

fn matches( &self, patterns: impl IntoIterator<Item = impl AsRef<Path>>, ) -> impl Iterator<Item = Result<PathBuf, PathBuf>>

Iterate over changed files that match the given patterns and patterns that don’t match any file.

If patterns is empty, all changed files are returned.

Source

fn resolve(&self, path: impl AsRef<Path>) -> PathBuf

Resolve a path to an absolute path.

Source

fn is_ignored(&self, path: impl AsRef<Path>) -> bool

Check if a file has been ignored.

Source

fn is_range_modified( &self, path: impl AsRef<Path>, range: (usize, usize), ) -> bool

Check if a range of lines in a file has been modified.

Provided Methods§

Source

fn check(&self, path: impl AsRef<Path>) -> Result<(), Vec<String>>

Check a file for dependent changes.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
