Required Associated Types

type Config: Clone + Default + 'static

A configuration type which is used for mapping between Self and the underlying value of Self::Signal.

type Signal: Clone + 'static

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.
