Trait Implementations

impl<Item> Clone for ArenaKey<Item>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Item> Debug for ArenaKey<Item>

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

Formats the value using the given formatter.

impl<Item> Deref for ArenaKey<Item>

type Target = usize

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<Item> Hash for ArenaKey<Item>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<Item> Index<ArenaKey<Item>> for Arena<Item>

type Output = Item

The returned type after indexing.

fn index(&self, index: ArenaKey<Item>) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<Item> IndexMut<ArenaKey<Item>> for Arena<Item>

fn index_mut(&mut self, index: ArenaKey<Item>) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl<Item> Ord for ArenaKey<Item>

fn cmp(&self, other: &Self) -> 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<Item> PartialEq for ArenaKey<Item>

fn eq(&self, other: &Self) -> 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<Item> PartialOrd for ArenaKey<Item>

fn partial_cmp(&self, other: &Self) -> 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.
