Struct Log

pub struct Log<T = LogData> {
    pub address: Address,
    pub data: T,
}

A log consists of an address, and some log data.

Fields

address: Address

The address which emitted this log.

data: T

The log data.

Implementations

impl Log

pub fn new( address: Address, topics: Vec<FixedBytes<32>>, data: Bytes, ) -> Option<Log>

Creates a new log.

pub const fn new_unchecked( address: Address, topics: Vec<FixedBytes<32>>, data: Bytes, ) -> Log

Creates a new log.

pub const fn empty() -> Log

Creates a new empty log.

impl<T> Log<T>

where &'a T: for<'a> Into<LogData>,

pub const fn new_from_event_unchecked(address: Address, data: T) -> Log<T>

Creates a new log.

pub fn new_from_event(address: Address, data: T) -> Option<Log<T>>

Creates a new log from an deserialized event.

pub fn reserialize(&self) -> Log

Reserialize the data.

Trait Implementations

impl<T> Clone for Log<T>

where T: Clone,

fn clone(&self) -> Log<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Log<T>

where T: Debug,

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

Formats the value using the given formatter.

impl Decodable for Log

fn decode(buf: &mut &[u8]) -> Result<Log, Error>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl<T> Default for Log<T>

where T: Default,

fn default() -> Log<T>

Returns the “default value” for a type.

impl<T> Deref for Log<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &<Log<T> as Deref>::Target

Dereferences the value.

impl<T> DerefMut for Log<T>

fn deref_mut(&mut self) -> &mut <Log<T> as Deref>::Target

Mutably dereferences the value.

impl Encodable for Log

fn encode(&self, out: &mut dyn BufMut)

Encodes the type into the out buffer.

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

impl<T> Encodable for Log<T>

where &'a T: for<'a> Into<LogData>,

fn encode(&self, out: &mut dyn BufMut)

Encodes the type into the out buffer.

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

impl<T> Hash for Log<T>

where T: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> PartialEq for Log<T>

where T: PartialEq,

fn eq(&self, other: &Log<T>) -> 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<T> Eq for Log<T>

where T: Eq,

impl<T> StructuralPartialEq for Log<T>
