Log

Struct Log 

Source
#[non_exhaustive]
pub struct Log { pub address: Address, pub data: Bytes, /* private fields */ }
Expand description

An EVM-style event log emitted during contract execution.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§address: Address

Emitting contract address.

§data: Bytes

Non-indexed data.

Implementations§

Source§

impl Log

Source

pub fn new_unchecked( address: Address, topics: Vec<B256>, data: impl Into<Bytes>, ) -> Self

Construct a log without checking the topic count.

Decoders use this to round-trip node responses even when malformed.

Source

pub fn new( address: Address, topics: Vec<B256>, data: impl Into<Bytes>, ) -> Option<Self>

Construct a log, returning None if it carries more than four topics.

Source

pub fn is_valid(&self) -> bool

Returns whether this log has at most four topics, as required by the EVM-compatible event log format.

Source

pub fn topics(&self) -> &[B256]

The indexed topics (topic0 = event signature hash).

Source

pub fn topics_mut(&mut self) -> &mut [B256]

The indexed topics, mutably. Grants access to the existing entries without allowing the list to grow past the topic limit.
