Function takeDelimiter [src]
Returns a slice of the next bytes of buffered data from the stream until
delimiter is found, advancing the seek position past the delimiter.
Returned slice excludes the delimiter. End-of-stream is treated equivalent
to a delimiter, unless it would result in a length 0 return value, in which
case null is returned instead.
If the delimiter is not found within a number of bytes matching the
capacity of this Reader, error.StreamTooLong is returned. In
such case, the stream state is unmodified as if this function was never
called.
Invalidates previously returned values from peek.
