Struct std::old_io::CharsUnstable

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

An iterator that reads a utf8-encoded character on each iteration, until .read_char() encounters EndOfFile.

Notes about the Iteration Protocol

The Chars 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.
