Expand description
A reader for owned data. See the module documentation for more information.
Fill the given bytes
argument with values. Exactly the length of the given slice must be filled, or else an error must be returned.
If this reader wraps a buffer of any kind, this function lets callers access contents of
the buffer without passing data through a buffer first.
If an implementation of peek_read
is provided, an implementation of this function
must be provided so that subsequent reads or peek-reads do not return the same bytes
