NOTE: This crate is deprecated. You should be using map(str::trim)
instead:
fn main() {
let text = " foo \r\n bar \n \n baz \n";
let mut lines = text.lines().map(str::trim);
assert_eq!(Some("foo"), lines.next());
assert_eq!(Some("bar"), lines.next());
assert_eq!(Some(""), lines.next());
assert_eq!(Some("baz"), lines.next());
assert_eq!(None, lines.next());
}
An extremely simple and tiny library which provides an iterator over the lines of a string, trimmed of whitespace. It is a simple wrapper around the Lines iterator in std::str which trims the whitespace from each line.
