control.protocol.read_line

read_line ( stdout : &mut R , pending : &mut Vec<u8> , limit : usize ) → Result<Option<Line>, Error> function [source] ¶ function [source] ¶ read_line: Read and classify one protocol line.

pending carries a line across calls. read_until appends what it read before it was cancelled, which is what makes this usable in select! -- read_line would lose those bytes, and would also reject the pane output that is not UTF-8.
