Trait Implementations

impl Clone for Approval

fn clone(&self) -> Approval

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Approval

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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

Convert into a [LogData] object.

fn into_log_data(self) -> LogData

Consume and convert into a [LogData] object.

impl PartialEq for Approval

fn eq(&self, other: &Approval) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SolEvent for Approval

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

The event’s ABI signature.

const SIGNATURE_HASH: B256 = _

const ANONYMOUS: bool = false

Whether the event is anonymous.

type DataTuple<'a> = (Uint<256>,)

The underlying tuple type which represents this event’s non-indexed parameters. These parameters are ABI encoded and included in the log body.

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

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

Convert decoded rust data to the event type.

fn check_signature( topics: &<Self::TopicList as SolType>::RustType, ) -> Result<()>

Check that the event’s signature matches the given topics.

fn tokenize_body(&self) -> Self::DataToken<'_>

Tokenize the event’s non-indexed parameters.

fn topics(&self) -> <Self::TopicList as SolType>::RustType

The event’s topics.

fn encode_topics_raw(&self, out: &mut [WordToken]) -> Result<()>

Encode the topics of this event into the given buffer.

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

Convert decoded rust data to the event type.

fn abi_encoded_size(&self) -> usize

The size of the ABI-encoded dynamic data in bytes.

fn encode_data_to(&self, out: &mut Vec<u8>)

ABI-encode the dynamic data of this event into the given buffer.

fn encode_data(&self) -> Vec<u8>

ABI-encode the dynamic data of this event.

fn encode_topics(&self) -> Vec<WordToken>

Encode the topics of this event.

fn encode_topics_array<const LEN: usize>(&self) -> [WordToken; LEN]

Encode the topics of this event into a fixed-size array.

fn encode_log_data(&self) -> LogData

Encode this event to a [LogData].

fn encode_log(log: &Log<Self>) -> Log

Transform ca [Log] containing this event into a [Log] containing [LogData].

fn decode_topics<I, D>( topics: I, ) -> Result<<Self::TopicList as SolType>::RustType, Error>

where I: IntoIterator<Item = D>, D: Into<WordToken>,

Decode the topics of this event from the given data.

fn abi_decode_data<'a>( data: &'a [u8], validate: bool, ) -> Result<<Self::DataTuple<'a> as SolType>::RustType, Error>

ABI-decodes the dynamic data of this event from the given buffer.

fn decode_raw_log<I, D>( topics: I, data: &[u8], validate: bool, ) -> Result<Self, Error>

where I: IntoIterator<Item = D>, D: Into<WordToken>,

Decode the event from the given log info.

fn decode_log_data(log: &LogData, validate: bool) -> Result<Self, Error>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
