vec_mut_scan
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.
