Trait EventHandler 

pub trait EventHandler {
    // Required method
    fn handle_event(&self, event: Event) -> Result<(), ReplayEvent>;
}

A trait implemented for objects handling events from EventsProvider.

An async variation also exists for implementations of EventsProvider that support async event handling. The async event handler should satisfy the generic bounds: F: core::future::Future<Output = Result<(), ReplayEvent>>, H: Fn(Event) -> F.

Required Methods

fn handle_event(&self, event: Event) -> Result<(), ReplayEvent>

Handles the given Event.

See EventsProvider for details that must be considered when implementing this method.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
