The log indexer backend interface.

Required Methods

fn is_indexed(&self) -> bool

Indicate whether the log indexing feature is supported.

fn filter_logs<'life0, 'async_trait>( &'life0 self, from_block: u64, to_block: u64, addresses: Vec<H160>, topics: Vec<Vec<Option<H256>>> ) -> Pin<Box<dyn Future<Output = Result<Vec<FilteredLog<Block>>, String>> + Send + 'async_trait>>

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

Filter the logs by the parameters.
