lisp_iter
Single-pass no-alloc iterator for simple lisp or lisp-like expressions.
use lisp_iter::LispIter;
fn main() {
let mut iter = LispIter::new(r#"(this-is-a-identifier :a 123 "wow") ; :a is shorthand for "a" "#);
let mut list = iter.next().unwrap().into_iter(); // Retrieve first list in iterator
println!("{:?}", list.next().unwrap()); // Identifier("this-is-a-identifier")
println!("{:?}", list.next().unwrap()); // Quote("a")
println!("{:?}", list.next().unwrap()); // Integer(0)
println!("{:?}", list.next().unwrap()); // Quote("wow")
}
Useful to glance over anything lispy with minimal to 0 overhead.
