Struct lfa::Table

pub struct Table<I: Hash + Eq, V>(pub HashMap<I, V>);

Generic tabular function representation.

Examples

Basic usage:

use lfa::{Function, Parameterised, Table};

let f = {
    let mut t = Table::<(u32, u32), f64>::new();
    t.update(&(0, 1), 1.0);

    t
};

assert_eq!(f.evaluate(&(0, 1)).unwrap(), 1.0);
