Struct Arc

pub struct Arc<T>(/* private fields */);

A reference-counted pointer to a value of type T stored in an ArcPool. Does not support weak references.

Implementations

impl<T> Arc<T>

pub fn get_mut(this: &mut Self) -> Option<&mut T>

pub fn into_inner(Self: Self) -> Option<T>

pub fn try_unwrap(Self: Self) -> Result<T, Self>

pub fn into_index(this: Self) -> ArcIndex<T>

pub fn ptr_eq(this: &Self, other: &Self) -> bool

pub unsafe fn from_index(pool: &ArcPool<T>, index: ArcIndex<T>) -> Self

Safety

Must be the same pool as the one that created the Arc

pub unsafe fn clone_from_index(pool: &ArcPool<T>, index: &ArcIndex<T>) -> Self

Safety

Must be the same pool as the one that created the Arc

pub fn ref_count(this: &Self) -> usize

pub fn is_unique(this: &Self) -> bool

Returns true if there are no other Arcs pointing to the same value.

This is equivalent to Arc::ref_count(this) == 1 but may be more performant.

Trait Implementations

impl<T> Clone for Arc<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Arc<T>

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

Formats the value using the given formatter.

impl<T> Deref for Arc<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: Hash> Hash for Arc<T>

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<T: Ord> Ord for Arc<T>

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<T: PartialEq> PartialEq for Arc<T>

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<T: PartialOrd> PartialOrd for Arc<T>

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.
