singlevec

For when you need a Vec, but intend to store only one item most of the time. In that case, that single item can be stored on the stack and will fall back to heap storage for multiple items.

Like a tinyvec::TinyVec<[T; 1]> that shares methods in common with both Vec and Option.

Simple and 100% safe code for a simple use case.
