Trait StatFunctionsSolution 

pub trait StatFunctionsSolution<T>: StatFunctionsGoal {
    // Required methods
    fn get_average(&self) -> Option<(T, f64)>;
    fn get_standard_deviation(&self) -> Option<(T, f64)>;
    fn get_success_rate<P>(&self, predicate: P) -> Option<f64>
       where P: Fn(&(T, f64)) -> bool;
}

The trait contains methods for calculate solution statistics for Vec<Option<Solution>> type Solution = (T, GoalValue);

Required Methods

fn get_average(&self) -> Option<(T, f64)>

Calculate an average of solutions and goal function. Returns None if self is empty or self contains None only.

fn get_standard_deviation(&self) -> Option<(T, f64)>

Calculate a standard deviation of solutions goal function. Returns None if length of self less 2 or self contains None only.

fn get_success_rate<P>(&self, predicate: P) -> Option<f64>

where P: Fn(&(T, f64)) -> bool,

Calculate success rate between 0 and 1. Returns Some(SR) if running count > 0 and None otherwise.

Params

predicate - function must return true for success solution and false otherwise.

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.
