Struct std::io::Lines[src]

pub struct Lines<'r, T> {
    // some fields omitted
}

An iterator that reads a line on each iteration, until .read_line() encounters EndOfFile.

Notes about the Iteration Protocol

The Lines may yield None and thus terminate an iteration, but continue to yield elements if iteration is attempted again.

Error

Any error other than EndOfFile that is produced by the underlying Reader is returned by the iterator and should be handled by the caller.
