Struct MethodSpecificity 

pub struct MethodSpecificity { /* private fields */ }

How specifically a method matched a particular call.

Carries the per-argument MatchScores plus their total; comparing two specificities (see compare_specificity) orders methods most-specific first for applicable-method selection.

Implementations

impl MethodSpecificity

pub fn new( method: Symbol, role: MethodRole, score: MatchScore, argument_scores: Vec<MatchScore>, ) -> Self

Builds a specificity record for a matched method.

pub fn method(&self) -> &Symbol

Returns the symbol identifying the matched method.

pub fn role(&self) -> MethodRole

Returns the matched method’s role in the combination.

pub fn score(&self) -> MatchScore

Returns the total match score across all arguments.

pub fn argument_scores(&self) -> &[MatchScore]

Returns the per-argument match scores, in argument order.

Trait Implementations

impl Clone for MethodSpecificity

fn clone(&self) -> MethodSpecificity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MethodSpecificity

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

Formats the value using the given formatter.

impl Eq for MethodSpecificity

impl PartialEq for MethodSpecificity

fn eq(&self, other: &MethodSpecificity) -> 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.
