Motivation
Try to resolve #.
This PR adds a method
take_value
to take the task local value of aTaskLocalFuture
.The
LocalKey::scope
function owns the slot value and drops it, but this method will allow you to re-acquire ownership of the slot value.Solution
Implemented method
take_value
for a pinnedTaskLocalFuture
.Maybe it is possible to provide non-pinned api as well (
pub fn take_value(&mut self) -> Option<T>
), but I'm not sure if it is worth providing both.
