}

Trait for user-provided event handlers.

Implement this to process specific event types during indexing.

Required Methods

fn handle<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, event: &'life1 DecodedEvent, ctx: &'life2 IndexContext, ) -> Pin<Box<dyn Future<Output = Result<(), IndexerError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Called for each decoded event that matches the handler’s schema.

fn schema_name(&self) -> &str

The event schema name this handler processes (e.g. "ERC20Transfer").
