Type Definition m_ipd::Strategy

type Strategy = fn() -> Box<dyn FnMut(Round) -> Choice>;

Represents a playing strategy

This function will be invoked one time every time two players play the IPD. The closure that is returned by the function will be repeatedly invoked with values of the Round enum; each invocation of the closure corresponds to one round of gameplay. The closure is told the other player’s choice in the previous round, and asked to return the next round’s choice.

A very simple strategy might be to always Cooperate. It could be written like this:

use m_ipd::*;
 
fn always_cooperate() -> Box<dyn FnMut(Round) -> Choice> {
    Box::new(|_| Cooperate)
}
 
let s: Strategy = always_cooperate;
