Struct Weighted 

pub struct Weighted<O: ?Sized>(/* private fields */);

Selects one operator per invocation based on assigned weights.

Each operator is paired with a NonZero<u16> weight. On each call, a random roll determines which operator runs. Higher weights mean higher probability.

Accepts a tuple of up to 16 (Operator, NonZero<u16>) pairs.

Examples

use evolve::operators::sequential::combinator::Weighted;
use evolve::operators::sequential::mutation::RandomReset;
use std::num::NonZero;

// 75% chance of first operator, 25% chance of second
let op = Weighted::new((
    (RandomReset::<u8>::new(), NonZero::new(3u16).unwrap()),
    (RandomReset::<u8>::new(), NonZero::new(1u16).unwrap()),
));
