Reads contiguous data from a stream into the provided slice.
The slice must be sized by the caller and will be populated up to its
capacity.

On success the amount of bytes read and a flag indicating the fin state
is returned as a tuple, or [`Done`] if there is no data to read.


Reads contiguous data from a stream into the provided slice . The slice must be sized by the caller and will be populated up to its capacity . On success the amount of bytes read and a flag indicating the fin state is returned as a tuple or [ ` Done ` ] if there is no data to read .
