Struct windows::RefCount [−][src]
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.
