pub struct Memo<P: Clone + Eq + Hash, T: Clone> { /* private fields */ }

Memorization for a parser.

It records the results of parsing a given position in the source code, including the parsed value and the position to which the parser was advanced.

pub fn get(&self, pos: &P) -> Option<(T, P)>

Get a memoized value.

pub fn insert(&self, pos: P, value: (T, P))

Insert a memoized value.
