Events#
The Event class in packages/eth_rpc/src/eth_rpc/event.py is a crucial component for handling Ethereum events. Here's an overview of its functionality and usage:
Event Class#
The Event class is a Generic class representing an Ethereum event and provides methods to interact with it. In order to define the schema of the event, you need to define a pydantic class with the appropriate fields, annotated with Indexed when necessary.
from typing import Annotated
from eth_rpc import Event
from eth_rpc.types import Indexed
from pydantic import BaseModel
class V2SwapEventType(BaseModel):
sender: Annotated[primitives.address, Indexed]
amount0_in: primitives.uint256
amount1_in: primitives.uint256
amount0_out: primitives.uint256
amount1_out: primitives.uint256
to: Annotated[primitives.address, Indexed]
Once you have defined the BaseModel for the event's interface, you need to create an Event instance that has the Event Type as a Generic Argument.
