Struct Log 

pub struct Log {
    pub address: String,
    pub topics: Vec<String>,
    pub data: Bytes,
    pub block_number: u64,
    pub tx_hash: String,
    pub tx_index: u64,
    pub block_hash: String,
    pub index: u64,
    pub removed: bool,
}

Log represents an protobuf compatible Ethereum Log that defines a contract log event. These events are generated by the LOG opcode and stored/indexed by the node.

NOTE: address, topics and data are consensus fields. The rest of the fields are derived, i.e. filled in by the nodes, but not secured by consensus.

Fields

address: String

address of the contract that generated the event

topics: Vec<String>

topics is a list of topics provided by the contract.

data: Bytes

data which is supplied by the contract, usually ABI-encoded

block_number: u64

block_number of the block in which the transaction was included

tx_hash: String

tx_hash is the transaction hash

tx_index: u64

tx_index of the transaction in the block

block_hash: String

block_hash of the block in which the transaction was included

index: u64

index of the log in the block

removed: bool

removed is true if this log was reverted due to a chain reorganisation. You must pay attention to this field if you receive logs through a filter query.

Trait Implementations

impl Clone for Log

fn clone(&self) -> Log

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Log

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

Formats the value using the given formatter.

impl Default for Log

fn default() -> Self

Returns the “default value” for a type.

impl Message for Log

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Log

fn eq(&self, other: &Log) -> 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.
