A crate that provides the user with two fast "vec-like" vecs that are backed by
a single vec. The caveat is that the operations like push and truncate
may rearrange the order of the other vec in an unspecified way.
Also provides a
retain_mut_unordered function to both the regular
Vec as well as
the two "vec-like" vecs provided by this crate.
Retain only elements that satisfy the predicate. May rearrange elements in the process.
