Returns the Span's start position.

Examples

let input = Rc::new(StringInput::new("ab".to_owned()));
let start = Position::from_start(input);
let end = start.clone().match_string("ab").unwrap();
let span = start.span(end);

assert_eq!(span.start(), 0);

Returns the Span's end position.

Examples

let input = Rc::new(StringInput::new("ab".to_owned()));
let start = Position::from_start(input);
let end = start.clone().match_string("ab").unwrap();
let span = start.span(end);

assert_eq!(span.end(), 2);

Splits the Span into a pair of Positions.

Examples

let input = Rc::new(StringInput::new("ab".to_owned()));
let start = Position::from_start(input);
let end = start.clone().match_string("ab").unwrap();
let span = start.clone().span(end.clone());

assert_eq!(span.split(), (start, end));

Captures a &str slice from the Input defined by the Span.

Examples

let input = Rc::new(StringInput::new("abc".to_owned()));
let start = Position::from_start(input).skip(1).unwrap();
let end = start.clone().match_string("b").unwrap();
let span = start.span(end);

assert_eq!(span.as_str(), "b");
