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 copy 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

impl StructuralPartialEq for LogData

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
