Add
Mutex::into_inner
method that consumes mutexand return underlying value.
I'm not sure what to test here, so I didn't add any tests.
Fixes #2211
Motivation
There are cases when you need to get ownership over the underlying value.
Also, both
std::sync::Mutex
andfutures::sync::Mutex
have the methodsinto_inner
that allow you to consume the mutex and get the owned value from it.Solution
Add
into_inner
method forsync::Mutex
that simply callsinto_inner
on innerUnsafeCell
