Trait Fraction 

pub trait Fraction<T>: Sized {
    // Required methods
    fn numerator(&self) -> T;
    fn denominator(&self) -> T;
    fn inv(&self) -> Option<Self>;
}

A fraction p/q with integers p and q.

p is called the numerator and q is called the denominator.

Required Methods

fn numerator(&self) -> T

Returns the numerator p

fn denominator(&self) -> T

Returns the denominator q

fn inv(&self) -> Option<Self>

Returns the multiplicative inverse q/p for fraction p/q.

If p is zero, None is returned.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
