Trait Map 

pub trait Map: Copy + Send {
    type I;
    type O;

    // Required method
    fn map(&self, i: Self::I) -> Self::O;
}

Function-like mapper from one value to one value.

Required Associated Types

type I

Input type.

type O

Output type.

Required Methods

fn map(&self, i: Self::I) -> Self::O

Maps one input value.

Dyn Compatibility

This trait is not dyn compatible.

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