Struct Id 

pub struct Id<K> { /* private fields */ }

A generational-arena key: the index names the slot, the generation names the occupant. Stale keys fail lookup.

Implementations

impl<K> Id<K>

pub fn index(self) -> usize

Trait Implementations

impl<K: Clone> Clone for Id<K>

fn clone(&self) -> Id<K>

impl<K: Ord> Ord for Id<K>

fn cmp(&self, other: &Id<K>) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl<K: PartialEq> PartialEq for Id<K>

fn eq(&self, other: &Id<K>) -> bool

Equality operator ==.

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

Inequality operator !=.

impl<K: PartialOrd> PartialOrd for Id<K>

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

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
