Methods for mapping an integer by its parity

Provided Methods

fn map_odd<F>(self, odd_fn: F) -> Result<Self, MapOddErr>

where F: FnOnce(Self) -> Result<Self, MapOddErr>,

Applies a function to self if it’s odd.

Errors

If self is odd, but the function called on it fails, an MapOddError is returned.

fn map_even<F>(self, even_fn: F) -> Result<Self, MapEvenErr>

where F: FnOnce(Self) -> Result<Self, MapEvenErr>,

Applies a function to self if it’s even.

Errors

If self is even, but the function called on it fails, a MapEvenError is returned.

fn parity_map<Odd, Even>( self, even_fn: Even, odd_fn: Odd, ) -> Result<Self, Either<MapEvenErr, MapOddErr>>

where Odd: FnOnce(Self) -> Result<Self, MapOddErr>, Even: FnOnce(Self) -> Result<Self, MapEvenErr>,

Applies even_fn to self if it’s even, else odd_fn is applied.

Errors

If self is even, but the function called on it fails, a MapEvenError is returned.

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.
