Trait MapFn 

pub trait MapFn<T> {
    type Output: Debug;

    // Required method
    fn apply(&self, t: T) -> Self::Output;
}

Essentially Fn (T) -> Output.

Required Associated Types

type Output: Debug

Required Methods

fn apply(&self, t: T) -> Self::Output

Map T to Output.

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

Implementations on Foreign Types

impl<I, O> MapFn<I> for fn(I) -> O

where O: Debug,

type Output = O
