Struct RefWithCost

pub struct RefWithCost<'a, N, T: 'a> {
    pub object: &'a T,
    pub cost: N,
}

A reference packed with a cost value.

Fields

object: &'a T

The reference to an object.

cost: N

The cost of the object.

Implementations

impl<'a, N, T> RefWithCost<'a, N, T>

pub fn new(object: &'a T, cost: N) -> RefWithCost<'a, N, T>

Creates a new reference packed with a cost value.

Trait Implementations

impl<'a, N: PartialOrd, T> Ord for RefWithCost<'a, N, T>

fn cmp(&self, other: &RefWithCost<'a, N, T>) -> 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<'a, N: PartialEq, T> PartialEq for RefWithCost<'a, N, T>

fn eq(&self, other: &RefWithCost<'a, N, T>) -> 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<'a, N: PartialOrd, T> PartialOrd for RefWithCost<'a, N, T>

fn partial_cmp(&self, other: &RefWithCost<'a, N, T>) -> 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.
