Struct RcA 

pub struct RcA<T, A: Allocator> { /* private fields */ }

A single-threaded reference-counting pointer. ‘Rc’ stands for ‘Reference Counted’.

Note: does not currently support DSTs as this would require various unstable library features but RcSlice and RcStr may be used instead. Dyn values must be boxed.

Implementations

impl<T, A: Allocator> RcA<T, A>

pub fn new(v: T) -> Self

where A: Default,

Allocate a new Rc and move v into it.

pub fn new_in(v: T, a: A) -> Self

Allocate a new Rc in specified allocator and move v into it.

pub fn allocator(this: &Self) -> &A

Returns a reference to the underlying allocator.

pub fn as_ptr(this: &Self) -> *const T

Provides a raw pointer to the data.

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

Returns a mutable reference to the contained value if data is not shared.

Otherwise returns None.

Trait Implementations

impl<T, A: Allocator> Borrow<T> for RcA<T, A>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T, A: Allocator> Clone for RcA<T, A>

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, A: Allocator> Debug for RcA<T, A>

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

Formats the value using the given formatter.

impl<T, A: Allocator> Deref for RcA<T, A>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: Display, A: Allocator> Display for RcA<T, A>

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

Formats the value using the given formatter.

impl<T, A: Allocator> Drop for RcA<T, A>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<T: Hash, A: Allocator> Hash for RcA<T, A>

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, A: Allocator> Ord for RcA<T, A>

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, A: Allocator> PartialEq for RcA<T, A>

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, A: Allocator> PartialOrd for RcA<T, A>

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.
