    // Required method
    fn select<R: Rng>(&self, population: &[(G, f64)], rng: &mut R) -> usize;

    // Provided method

Expand description

Selection operator trait

Selects individuals from a population for reproduction.

Required Methods§

Source

fn select<R: Rng>(&self, population: &[(G, f64)], rng: &mut R) -> usize

Select a single individual from the population

Returns the index of the selected individual.

Provided Methods§

Source

fn select_many<R: Rng>( &self, population: &[(G, f64)], count: usize, rng: &mut R, ) -> Vec<usize>

Select multiple individuals from the population

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
