# ThinArray

This is a thin array type, meant to be an alternative to `Box<[T]>` when you have more arrays than actual data in them. It's only as big as one usize, and doesn't allocate for an empty array.
It stores the array length with the data, whereas `Box<[T]>` stores it with the pointer. That helps with memory usage in many cases, with only the minor downside that accessing the length needs one more pointer indirection, unless it's 0. `is_empty` avoids that indirection.
