    // Required method

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.

Implementations on Foreign Types

impl NeverMapIntoExtension for Infallible

fn map_into<T>() -> impl Fn(Infallible) + Signal + Clone

A mapper for the never type into anything. Since Never cannot be created, nothing has to be actually converted.

The implementation is just: |_| unreachable!().
