Struct Log

pub struct Log {
    pub address: Vec<u8>,
    pub topics: Vec<Vec<u8>>,
    pub data: Vec<u8>,
    pub index: u32,
    pub block_index: u32,
    pub ordinal: u64,
}

Fields

address: Vec<u8>

topics: Vec<Vec<u8>>

data: Vec<u8>

index: u32

Index is the index of the log relative to the transaction. This index is always populated regardless of the state reversion of the the call that emitted this log.

Only available in DetailLevel: EXTENDED

block_index: u32

BlockIndex represents the index of the log relative to the Block.

An important notice is that this field will be 0 when the call that emitted the log has been reverted by the chain.

Currently, there is two locations where a Log can be obtained:

• block.transaction_traces[].receipt.logs[]
• block.transaction_traces[].calls[].logs[]

In the receipt case, the logs will be populated only when the call that emitted them has not been reverted by the chain and when in this position, the blockIndex is always populated correctly.

In the case of calls case, for call where stateReverted == true, the blockIndex value will always be 0.

ordinal: u64

The block’s global ordinal when the log was recorded, refer to [Block] documentation for further information about ordinals and total ordering.

Trait Implementations

impl AsRef<Log> for Log

fn as_ref(&self) -> &Log

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<Log> for LogView<'_>

fn as_ref(&self) -> &Log

Converts this type into a shared reference of the (usually inferred) input type.

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<(), Error>

Formats the value using the given formatter.

impl Default for Log

fn default() -> Log

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where 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( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where 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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where 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.
