pub struct Sticky<T> { /* fields omitted */ }A Sticky<T> keeps a value T stored in a thread.
This type works similar in nature to Fragile<T> and exposes the
same interface. The difference is that whereas Fragile<T> has
its destructor called in the thread where the value was sent, a
Sticky<T> that is moved to another thread will have the internal
destructor called when the originating thread tears down.
As this uses TLS internally the general rules about the platform limitations
of destructors for TLS apply.
Creates a new Sticky wrapping a value.
The value that is moved into the Sticky can be non Send and
will be anchored to the thread that created the object. If the
sticky wrapper type ends up being send from thread to thread
only the original thread can interact with the value.
Consumes the Sticky, returning the wrapped value.
Panics if called from a different thread than the one where the
original value was created.
Consumes the Sticky, returning the wrapped value if successful.
The wrapped value is returned if this is called from the same thread
as the one where the original value was created, otherwise the
Sticky is returned as Err(self).
Immutably borrows the wrapped value.
Panics if the calling thread is not the one that wrapped the value.
For a non-panicking variant, use try_get.
Mutably borrows the wrapped value.
Panics if the calling thread is not the one that wrapped the value.
For a non-panicking variant, use try_get_mut.
Tries to immutably borrow the wrapped value.
Returns None if the calling thread is not the one that wrapped the value.
Tries to mutably borrow the wrapped value.
Returns None if the calling thread is not the one that wrapped the value.
