Struct EventFilter 

pub struct EventFilter { /* private fields */ }

Type representing filters to apply when fetching events from the chain.

Examples

use alloy::primitives::address;
use event_scanner::EventFilter;

pub async fn create_event_filter() -> EventFilter {
    let contract_address = address!("0xd8dA6BF26964af9d7eed9e03e53415d37aa96045");
    let filter = EventFilter::new()
        .contract_address(contract_address)
        .event("Transfer(address,address,uint256)");

    filter
}

Implementations

impl EventFilter

pub fn new() -> Self

Creates a new EventFilter.

pub fn contract_address(self, contract_address: impl Into<Address>) -> Self

Sets the contract address to filter events from. If not set, events from all contracts will be tracked.

pub fn contract_addresses( self, contract_addresses: impl IntoIterator<Item = impl Into<Address>>, ) -> Self

Sets the contract address to filter events from. If not set, events from all contracts will be tracked.

pub fn event(self, event: impl Into<String>) -> Self

Sets the event signature to filter specific events. If neither events nor event signature hashes are set, all events from the specified contract(s) will be tracked.

pub fn events(self, events: impl IntoIterator<Item = impl Into<String>>) -> Self

Sets the event signatures to filter specific events. If neither events nor event signature hashes are set, all events from the specified contract(s) will be tracked.

pub fn event_signature(self, event_signature: impl Into<Topic>) -> Self

Sets the event signature hash to filter specific events. If neither event signature hashes nor events are set, all events from the specified contract(s) will be tracked.

pub fn event_signatures( self, event_signatures: impl IntoIterator<Item = impl Into<Topic>>, ) -> Self

Sets the event signature hashes to filter specific events. If neither event signature hashes nor events are set, all events from the specified contract(s) will be tracked.
