tinyvec

A 100% safe crate of vec-like types. #![forbid(unsafe_code)]

Main types are as follows:

ArrayVec is an array-backed vec-like data structure. It panics on overflow.
SliceVec is the same deal, but using a &mut [T].
TinyVec (alloc feature) is an enum that's either an Inline(ArrayVec) or a Heap(Vec). If a TinyVec is Inline and would overflow it automatically transitions to Heap and continues whatever it was doing.

To attain this "100% safe code" status there is one compromise: the element type of the vecs must implement Default.
