Trait BatchEventHandler 

pub trait BatchEventHandler {
    type Error;

    // Required method
    fn handle_event(&mut self, event: BatchEvent) -> Result<(), Self::Error>;

    // Provided method
    fn handle_events(
        &mut self,
        events: Vec<BatchEvent>,
    ) -> Result<(), Self::Error> { ... }
}

Available on crate feature std only.

A handler for batch events.

Implementations receive events as they are processed from the blockchain and update internal state accordingly.

Required Associated Types

type Error

The error type returned when handling fails.

Required Methods

fn handle_event(&mut self, event: BatchEvent) -> Result<(), Self::Error>

Handles a batch event.

Implementations should update any internal state (e.g., batch store) based on the event.

Provided Methods

fn handle_events(&mut self, events: Vec<BatchEvent>) -> Result<(), Self::Error>

Handles a batch of events atomically.

The default implementation calls handle_event for each event, but implementations may override this for better performance or transactional semantics.

Dyn Compatibility

This trait is dyn compatible.

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