Tiny-Vec
A dynamic array with an initial stack-based buffer, for small collections.
It aims to have a similar API to std::vec::Vec, but allowing to optimize small lists. It starts as a stack-based buffer, and automatically switches to the heap when the capacity grows over a certain number of elements.
The tiny-str crate provides TinyString, which is a String backed by a TinyVec, just like std::string::String is built on top of std::vec::Vec.

== Features == These features are only usable on nightly compilers, that's why they are disabled by default.
use-specialization Enables specialization for trait impls For example, From<&[T]> where T is Copy can be optimized as a ptr::copy. We can specialize that case, while still allowing From<&[T]> for the types that only implement Clone.
default-size Adds the option to not specify a capacity for the stack buffer, which will default to the maximun capacity that fits in the RawVec's space. This default size causes no memory waste when switching to the heap.
