Struct LogData

pub struct LogData {
    pub data: Bytes,
    /* private fields */
}

An Ethereum event log object.

Fields

data: Bytes

The plain data.

Implementations

impl LogData

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

Creates a new log, without length-checking. This allows creation of invalid logs. May be safely used when the length of the topic list is known to be 4 or less.

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

Creates a new log.

pub const fn empty() -> LogData

Creates a new empty log.

pub fn is_valid(&self) -> bool

True if valid, false otherwise.

pub fn topics(&self) -> &[FixedBytes<32>]

Get the topic list.

pub fn topics_mut(&mut self) -> &mut [FixedBytes<32>]

Get the topic list, mutably. This gives access to the internal array, without allowing extension of that array.

pub fn topics_mut_unchecked(&mut self) -> &mut Vec<FixedBytes<32>>

Get a mutable reference to the topic list. This allows creation of invalid logs.

pub fn set_topics_unchecked(&mut self, topics: Vec<FixedBytes<32>>)

Set the topic list, without length-checking. This allows creation of invalid logs.

pub fn set_topics_truncating(&mut self, topics: Vec<FixedBytes<32>>)

Set the topic list, truncating to 4 topics.

pub fn split(self) -> (Vec<FixedBytes<32>>, Bytes)

Consumes the log data, returning the topic list and the data.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for LogData

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<LogData, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<LogData, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Arbitrary for LogData

type Parameters = (<Vec<FixedBytes<32>> as Arbitrary>::Parameters, <Bytes as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<Vec<FixedBytes<32>> as Arbitrary>::Strategy, <Bytes as Arbitrary>::Strategy), fn((Vec<FixedBytes<32>>, Bytes)) -> LogData>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _top: <LogData as Arbitrary>::Parameters, ) -> <LogData as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for LogData

fn clone(&self) -> LogData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogData

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

Formats the value using the given formatter.

impl Default for LogData

fn default() -> LogData

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LogData

fn deserialize<__D>( __deserializer: __D, ) -> Result<LogData, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for LogData

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 IntoLogData for LogData

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 LogData

fn eq(&self, other: &LogData) -> 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 Serialize for LogData

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for LogData
