Struct sise::Parser

pub struct Parser<'a> { /* private fields */ }

Parser that decodes a SISE file into a sequence of ParsedItem.

Example

let data = "(test (1 2 3))";
let mut parser = sise::Parser::new(data);
assert_eq!(parser.next_item().unwrap(), sise::ParsedItem::ListStart(0));
assert_eq!(
    parser.next_item().unwrap(),
    sise::ParsedItem::Atom("test", 1),
);
assert_eq!(parser.next_item().unwrap(), sise::ParsedItem::ListStart(6));
assert_eq!(parser.next_item().unwrap(), sise::ParsedItem::Atom("1", 7));
assert_eq!(parser.next_item().unwrap(), sise::ParsedItem::Atom("2", 9));
assert_eq!(parser.next_item().unwrap(), sise::ParsedItem::Atom("3", 11));
assert_eq!(parser.next_item().unwrap(), sise::ParsedItem::ListEnd(12));
assert_eq!(parser.next_item().unwrap(), sise::ParsedItem::ListEnd(13));
parser.finish().unwrap();
