Trait EachCrateIndividual

Source

pub trait EachCrateIndividual {
    type Item;

    // Required methods
    fn new(individual: &Rc<Individual<Self::Item>>) -> Self;
    fn get_individual(&self) -> &Individual<Self::Item>;

    // Provided methods

Expand description

A trait for inividual defined by each crete.

A struct implmented this must have Rc<Individual<T>>.

T - A type of value.

§Example

use std::rc::Rc;
use scarlet_queen_core::each_individual::{Individual, EachCrateIndividual};

#[derive(PartialEq, Eq, Debug)]
struct SampleIndividual(Rc<Individual<u8>>);

impl EachCrateIndividual for SampleIndividual {
    type Item = u8;

    fn new(individual: &Rc<Individual<Self::Item>>) -> Self {
        SampleIndividual(Rc::clone(&individual))
    }

    fn get_individual(&self) -> &Individual<Self::Item> {
        self.0.as_ref()
    }
}

let r: Rc<Individual<u8>> = Rc::new(Individual::new(5u8));
let sample: SampleIndividual = SampleIndividual::new(&r);

assert_eq!(sample.get_individual(), r.as_ref());
assert_eq!(sample.get_id(), r.get_id());
assert_eq!(sample.get_value(), r.get_value());
