S-Expressions Parser and Printer
§Parser example
use s_expr::{Parser, Element, Span};
let mut parser = Parser::new("(let x 1)");
let r = parser.next().expect("parse data").expect("not end of stream");
let elements = r.inner.paren().expect("paren group");
assert_eq!(elements[0].inner.atom().and_then(|atom| atom.ident()), Some("let"));
assert_eq!(elements[0].span, Span::on_line(1, 1, 4));Structs§
