    pub variables: FxHashSet<Spur>,
    pub quality: u32,
    pub pattern_type: PatternType,
}

Implementations

impl Pattern

pub fn new(terms: Vec<TermId>) -> Self

Create a new pattern

pub fn extract_variables(&mut self, manager: &TermManager)

Extract variables from the pattern

pub fn calculate_quality(&mut self, manager: &TermManager)

Calculate pattern quality

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Pattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Pattern

fn eq(&self, other: &Pattern) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Pattern

impl StructuralPartialEq for Pattern
