Struct MatchScore 

pub struct MatchScore(/* private fields */);

A match quality score used to rank shapes during overload selection.

Higher scores are preferred; reject marks a non-match.

Implementations

impl MatchScore

pub fn exact(value: i32) -> Self

Build a score from an explicit integer weight.

pub fn reject() -> Self

The score that marks a rejected match (far below any accept).

pub fn value(self) -> i32

The underlying integer weight.

Trait Implementations

impl AddAssign for MatchScore

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

impl Clone for MatchScore

fn clone(&self) -> MatchScore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MatchScore

impl Debug for MatchScore

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

Formats the value using the given formatter.

impl Default for MatchScore

fn default() -> MatchScore

Returns the “default value” for a type.

impl Eq for MatchScore

impl Ord for MatchScore

fn cmp(&self, other: &MatchScore) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MatchScore

fn eq(&self, other: &MatchScore) -> 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 PartialOrd for MatchScore

fn partial_cmp(&self, other: &MatchScore) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
