Gives access to methods for mapping based on a number’s parity.

Required Methods

fn parity(&self) -> Parity

Returns the parity of &self

Provided Methods

fn parity_map( self, odd: impl FnOnce(Self) -> Self, even: impl FnOnce(Self) -> Self ) -> Self

Returns odd(self) if self is odd, else even(self).

fn parity_map_and_then<F>( self, odd: impl FnOnce(Self) -> Self, even: impl FnOnce(Self) -> Self, after: impl FnOnce(Self) -> Self ) -> Self

Calls a function on the result of self.parity_map(..), returning the result.

fn map_even(self, f: impl FnOnce(Self) -> Self) -> Self

Returns f(self) if self is even, else self.

fn map_odd(self, f: impl FnOnce(Self) -> Self) -> Self

Returns f(self) if self is odd, else self.
