Forward scan over a vector with mutation and item removal.

Provides an iterator like interface over a vector which allows mutation and removal of items. Items are kept in order and every item is moved at most once, even when items are removed. Dropping the VecMutScan mid-iteration keeps remaining items in the vector.

This can be seen as an extension of Vec's retain and drain. It is also very similar to the unstable drain_filter but slightly more flexible. Unlike drain_filter this specifies the drop behavior (to keep all following elements). It also doesn't require the filtering to be done within a closure, which gives additional flexibilty at the cost of not being able to implement the Iterator trait.
