Trait nommy::Peek

pub trait Peek<T>: Sized {
    fn peek(input: &mut impl Buffer<T>) -> bool;
}

An interface with dealing with parser-peeking. The required function peek takes in a Cursor iterator and will attempt to loosely parse the data provided, asserting that if the equivalent Buffer is given to the Parse::parse function, it should succeed.

use nommy::{Peek, Buffer, IntoBuf, text::Tag};
let mut buffer = ".".chars().into_buf();
assert!(Tag::<".">::peek(&mut buffer.cursor()));
