This PR adds a
into_inner
function toHandle
.Being able to go back to the database can be useful for methods that take a
Database
as argument but have to create aHandle
because they run concurrent code.It is then desired that the method can return a
Database
to avoid that the entire code base has to use aHandle<Db>
.Example:
Why not just pass in a
Handle
This is a possibility but it leaks that the function uses concurrency internally and one also has to be careful to pass in a
&mut Handle<T>
and to not clone it on the call-site (which I did) because it then results in a dead lock when callingget_mut
.
