Struct windows::RefCount[−][src]

#[repr(transparent)]
pub struct RefCount(_);
Expand description

A thread-safe reference count for use with COM/HSTRING implementations.

Implementations

impl RefCount[src]

pub fn new(count: u32) -> Self[src]

Creates a new RefCount with an initial value of 1.

pub fn add_ref(&self) -> u32[src]

Increments the reference count, returning the new value.

pub fn release(&self) -> u32[src]

Decrements the reference count, returning the new value.

This operation inserts an Acquire fence when the reference count reaches zero. This prevents reordering before the object is destroyed.
