Trait UseContext

pub trait UseContext {
    type Message;

    // Required method
    fn use_context<T, F>(&self, f: F) -> ContextValue<T>
       where T: 'static + Clone + PartialEq,
             F: Fn(T) -> Self::Message + 'static;
}

Functional component for using the context.

where T: 'static + Clone + PartialEq, F: Fn(T) -> Self::Message + '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.
