small_vec

A dynamic array or vector supporting small buffer optimization.

---

SmallVec<T, N> is, in essence, just an enum with two variants:

• LocalBuf: a buffer allocated locally inside the SmallVec itself.
• RemoteBuf: a Vec<T>, i.e., a remote buffer allocated on the heap.

The capacity of the local buffer is specified at compile time as a constant generic argument to SmallVec thanks to const generics.
