Canrun is a logic programming library inspired by the *Kanren family of language DSLs.

I'm still quite new to both Rust and logic programming, so there are likely to be rough edges. At best it may be a useful implementation of something that resembles the core concepts of a Kanren while being idiomatically Rusty. At worst it may just be a poor misinterpretation with fatal flaws.
use canrun::{Goal, both, unify, var};
use canrun::example::I32;
let x = var();
let y = var();
let goal: Goal<I32> = both(unify(x, y), unify(1, x));
let result: Vec<_> = goal.query(y).collect();
assert_eq!(result, vec![1])
