Struct darc::Arc

pub struct Arc<T: ?Sized> { /* private fields */ }

A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically Reference Counted’.

Implementations

impl<T> Arc<T>

pub fn new(data: T) -> Self

Constructs a new Arc<T>.

pub fn from_rc(rc: Rc<T>) -> Self

Converts an Rc<T> to Arc<T>. This changes its count to start using atomic access, even in other outstanding Rc<T> references to the same underlying object.

Trait Implementations

impl<T: ?Sized> AsRef<T> for Arc<T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: ?Sized> Borrow<T> for Arc<T>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T: ?Sized> Clone for Arc<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized + Debug> Debug for Arc<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Arc<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: ?Sized> Deref for Arc<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: ?Sized + Display> Display for Arc<T>

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

Formats the value using the given formatter.

impl<T> From<T> for Arc<T>

fn from(data: T) -> Self

Converts to this type from the input type.

impl<T: ?Sized + 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: ?Sized + 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) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<T: ?Sized + PartialEq> PartialEq<Arc<T>> for Arc<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: ?Sized + PartialOrd> PartialOrd<Arc<T>> 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: &Self) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Self) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Self) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Self) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T: ?Sized> Pointer for Arc<T>

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

Formats the value using the given formatter.

impl<T: ?Sized + Eq> Eq for Arc<T>

impl<T: Send + Sync + ?Sized> Send for Arc<T>

impl<T: Send + Sync + ?Sized> Sync for Arc<T>

impl<T: RefUnwindSafe + ?Sized> UnwindSafe for Arc<T>
