Trait Functor 

pub trait Functor<A> {
    type Mapped<B>;

    // Required method
    fn fmap<B, F: Fn(A) -> B>(self, f: F) -> Self::Mapped<B>;
}

Rust-level Functor trait.

Required Associated Types

type Mapped<B>

The mapped-over container type.

Required Methods

fn fmap<B, F: Fn(A) -> B>(self, f: F) -> Self::Mapped<B>

Apply f to every element.

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.
