Struct ImmutableWeakString

pub struct ImmutableWeakString<TAllocator = StdAllocator>
where
    TAllocator: Allocator,
{ /* private fields */ }

Represents a weak reference to an ImmutableString. Analogously to how ImmutableWeakArray is a weak reference to ImmutableArray.

Implementations

impl<TAllocator: Allocator> ImmutableWeakString<TAllocator>

pub fn upgrade(&self) -> Option<ImmutableString<TAllocator>>

Upgrades the ImmutableWeakString to an ImmutableString.

Returns None if the ImmutableWeakString is no longer valid, i.e. the underlying memory has been deallocated. Otherwise returns a new strong

pub fn strong_count(instance: &Self) -> usize

Returns the number of strong references to the ImmutableWeakString.

pub fn weak_count(instance: &Self) -> usize

Returns the number of weak references to the ImmutableWeakString.

pub fn release(self) -> bool

Releases the ImmutableWeakString. If this was the last weak reference, it will deallocated the underlying memory and return true. Otherwise it will just return false.

Trait Implementations

impl<TAllocator> Clone for ImmutableWeakString<TAllocator>

where TAllocator: Allocator + Clone,

fn clone(&self) -> ImmutableWeakString<TAllocator>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<TAllocator: Allocator> Drop for ImmutableWeakString<TAllocator>

fn drop(&mut self)

Executes the destructor for this type.
