[−][src]Struct egg::AstDepth

pub struct AstDepth;

A simple CostFunction that counts maximum ast depth.

use egg::{*, recexpr as r};

let e: RecExpr<String> = r!("+", r!("foo"), r!("bar"), r!("baz"));
assert_eq!(AstDepth.cost_rec(&e), 2);

type Cost = usize

The Cost type. It only requires PartialOrd so you can use floating point types, but failed comparisons (NaNs) will result in a panic. Read more
