Struct IgnoreDependencyMatcher 

pub struct IgnoreDependencyMatcher { /* private fields */ }

Compiled ignoreDependencies entries.

Entries without glob metacharacters match a package name exactly. Entries with glob metacharacters (@acme/*, @types/*) use the same glob syntax as ignorePatterns, matched against the package name.

Implementations

impl IgnoreDependencyMatcher

pub fn compile(entries: &[String]) -> Self

Compile the configured ignoreDependencies entries.

Panics

Panics when a glob entry is invalid. Config loading validates every glob entry before resolution, so this does not happen for a loaded config.

pub fn is_empty(&self) -> bool

Whether no entries were configured.

pub fn is_ignored(&self, package_name: &str) -> bool

Whether package_name is excluded by an exact entry or a glob entry.

pub fn note_declared(&self, package_name: &str)

Record a name declared in a package.json dependency section. Only this check makes Self::unmatched_globs and Self::redundant_entries report anything.

pub fn suppresses(&self, package_name: &str) -> bool

Whether an entry hides the finding that a detector found for package_name. Call it only for a name that the detector reports when no entry matches it: every matching entry is then recorded as one that had an effect.

pub fn reset_usage(&self)

Forget the hits of an earlier analysis pass.

A long-lived process (watch mode, the LSP, an engine session) keeps one resolved config for many passes. Each dead-code pass calls this first, so a glob that matched in an earlier pass is reported again when its dependency is gone.

pub fn unmatched_globs(&self) -> Vec<&str>

Glob entries that matched no dependency this run, in config order.

Empty when no glob was configured or when no declared dependency was checked, because such a run says nothing about a typo.

pub fn redundant_entries(&self) -> Vec<&str>

Entries that hid no dependency finding this run, in config order.

A glob that matched no package name is left out, because Self::unmatched_globs reports it. Empty when no declared dependency was checked.
