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.
