Trait Implementations

impl Clone for Approval

fn clone(&self) -> Approval

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<&Approval> for LogData

fn from(this: &Approval) -> LogData

Converts to this type from the input type.

impl IntoLogData for Approval

fn to_log_data(&self) -> LogData

type DataToken<'a> = <<Approval as SolEvent>::DataTuple<'a> as SolType>::Token<'a>

The TokenSeq type corresponding to the tuple.

type TopicList = (FixedBytes<32>, Address, Address)

The underlying tuple type which represents this event’s topics.

const SIGNATURE: &'static str = "Approval(address,address,uint256)"

The event’s ABI signature.

const SIGNATURE_HASH: B256 = _

The event’s ABI signature hash, or selector: keccak256(SIGNATURE)

const ANONYMOUS: bool = false

Whether the event is anonymous.

fn new( topics: <Self::TopicList as SolType>::RustType, data: <Self::DataTuple<'_> as SolType>::RustType, ) -> Self
