Struct Filter

pub struct Filter { /* private fields */ }

A compiled pattern bound to the part of an identifier it describes.

The target travels with the filter so filename, path, folder, and type-name selectors all use the same Self::matches operation.

Implementations

impl Filter

pub const fn new(pattern: Pattern, target: PatternTarget) -> Self

Creates a positive filter.

pub fn with_exclusions( self, exclusions: impl IntoIterator<Item = Filter>, ) -> Self

Returns this filter with hard exclusions evaluated after the parent match.

pub fn not_matching(self) -> Self

Returns a filter with the pattern’s meaning inverted.

pub const fn pattern(&self) -> &Pattern

Returns the compiled pattern carried by this filter.

pub const fn target(&self) -> PatternTarget

Returns the candidate part carried by this filter.

pub fn exclusions(&self) -> &[Filter]

Returns hard exclusions in declaration order.

pub fn matches(&self, identifier: &str) -> bool

Returns whether this filter selects identifier.
