Trait Functor

pub trait Functor<U>: HKT<U> {
    // Required method
    fn fmap<F>(&self, f: F) -> Self::T
       where F: Fn(&Self::C) -> U;
}

Required Methods§

fn fmap<F>(&self, f: F) -> Self::T
where F: Fn(&Self::C) -> U,

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.
