Velect: A Vec with item selection

velect is a Rust crate that provides a vector-like type with item selection functionality - which here means either zero or one index from the vector is "selected" and can be retrieved easily without needing to manually track the index of the selected item

Velect does the index tracking for you - it maintains the selected index, updating it whenever a mutation necessitates it.

Interface

Velect implements Deref<Target = Vec<_>>, which allows you to use all non-mutating functions from Vec as well as [T] transparently. Mutating functions (those taking &mut self as a parameter) are reimplemented with compatible interfaces, helping make Velect a close-to-drop-in replacement for Vec.

Additionally, Velect<T> also implements many of the same traits as Vec<T>.
