Trait Context

pub trait Context: Clone + Copy {
    type Event;

    // Required method
    fn handle_event(&mut self, event: Event<Self::Event>);
}

Used to provide state that may affect behaviour when pressing the key.

e.g. the behaviour of layered::LayeredKey depends on which layers are active in layered::Context.

Required Associated Types

type Event

The type of Event the context handles.

Required Methods

fn handle_event(&mut self, event: Event<Self::Event>)

Used to update the Context’s state.

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.
