[−][src]Struct windows::RefCount
A thread-safe reference count for use with COM implementations.
Implementations
impl RefCount
[src]
pub fn new() -> RefCount
[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.
