Represents a specific index of raw event data.

Required Methods

fn name(&self) -> String

Return the name of this index.

This should be unique across all of the indices.

fn init_chain<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, dbtx: &'life1 mut PgTransaction<'_>, app_state: &'life2 Value, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

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

This will be called once when processing the genesis before the first block.

fn index_batch<'life0, 'life1, 'async_trait>( &'life0 self, dbtx: &'life1 mut PgTransaction<'_>, batch: EventBatch, context: EventBatchContext, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

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

This allows processing a batch of events, over many blocks.
