Trait Update

pub trait Update<State, Message> {
    // Required method
    fn update(
        &self,
        state: &mut State,
        message: Message,
    ) -> impl Into<Task<Message>>;
}

The update logic of some Application.

This trait allows the application builder to take any closure that returns any Into<Task<Message>>.

Required Methods

fn update( &self, state: &mut State, message: Message, ) -> impl Into<Task<Message>>

Processes the message and updates the state of the Application.

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.
