Move member
from the set at source
to the set at destination
.
This operation is atomic.
In every given moment the element will appear to be a member of source
or
destination
for other clients.
If the source set does not exist or does not contain the specified element, no
operation is performed and 0
is returned.
Otherwise, the element is removed from the source set and added to the
destination set.
When the specified element already exists in the destination set, it is only
removed from the source set.
An error is returned if source
or destination
does not hold a set value.
