		## Zero Copy

		### `bytes(from[, encoding])`

		### `bytes.sort(a, b)`

		### `bytes.compare(a, b)`

		### `bytes.native(from[, encoding])

		## Optimized (memcopy only when necessary)

		### `bytes.arrayBuffer(_from[, encoding])`

		## Memory Copy

		All binary API's that must do a memcopy are prefaced with `"memcopy"`.
