Struct ArenaId 

pub struct ArenaId<T> { /* private fields */ }

A type-safe identifier for elements stored in an Arena.

Uses phantom data to ensure type safety - an ArenaId<A> cannot be used to access elements from an Arena<B>.

Implementations

impl<T> ArenaId<T>

pub const fn new(id: u32) -> ArenaId<T>

Creates a new arena identifier from a raw u32 index.

Trait Implementations

impl<T> Clone for ArenaId<T>

fn clone(&self) -> ArenaId<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Copy for ArenaId<T>

impl<T: Debug> Debug for ArenaId<T>

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

Formats the value using the given formatter.

impl<T: Eq> Eq for ArenaId<T>

impl<T> From<i32> for ArenaId<T>

fn from(id: i32) -> Self

Converts to this type from the input type.

impl<T> From<u32> for ArenaId<T>

fn from(id: u32) -> Self

Converts to this type from the input type.

impl<T> From<usize> for ArenaId<T>

fn from(id: usize) -> Self

Converts to this type from the input type.

impl<T> Index<ArenaId<T>> for Arena<T>

type Output = T

The returned type after indexing.

fn index(&self, index: ArenaId<T>) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<T: Ord> Ord for ArenaId<T>

fn cmp(&self, other: &ArenaId<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<T: PartialEq> PartialEq for ArenaId<T>

fn eq(&self, other: &ArenaId<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<T: PartialOrd> PartialOrd for ArenaId<T>

fn partial_cmp(&self, other: &ArenaId<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.
