Struct thread_local::CachedThreadLocal
[−]
[src]
pub struct CachedThreadLocal<T: ?Sized + Send> {
// some fields omitted
}Wrapper around ThreadLocal which adds a fast path for a single thread.
This has the same API as ThreadLocal, but will register the first thread
that sets a value as its owner. All accesses by the owner will go through
a special fast path which is much faster than the normal ThreadLocal path.
