Small String

Create strings of any length on the stack, automatically upgrading to the heap when they become larger than the buffer. Also allows converting from a String for free (i.e. without copying to the stack even if they're small enough).

Backed by smallvec.

// Default maximum size to store on the stack: 8 bytes
let stack: SmallString = "Hello!".into();

// Reuses allocation
let heap: String = "Hello!".into();
let still_heap: SmallString = heap.into();
