Struct Event 

pub struct Event {
    pub package_id: Address,
    pub module: Identifier,
    pub sender: Address,
    pub type_: StructTag,
    pub contents: Vec<u8>,
}

An event

BCS

The BCS serialized form for this type is defined by the following ABNF:

event = address identifier address struct-tag bytes

Fields

package_id: Address

Package id of the top-level function invoked by a MoveCall command which triggered this event to be emitted.

module: Identifier

Module name of the top-level function invoked by a MoveCall command which triggered this event to be emitted.

sender: Address

Address of the account that sent the transaction where this event was emitted.

type_: StructTag

The type of the event emitted

contents: Vec<u8>

BCS serialized bytes of the event

Implementations

impl Event

pub fn digest(&self) -> Digest

Available on crate features hash and serde only.

Per-event digest used as the leaf input for authenticated event stream commitments.

Unlike the TransactionEvents digest above, this is not salted with the type name: the framework computes it as the bare BLAKE2b-256 over the BCS-encoded Event. Two events with identical contents share a digest; their merkle leaves remain distinct because the surrounding EventCommitment also pins each event to its (checkpoint_seq, transaction_idx, event_idx) position.

Trait Implementations

impl Arbitrary for Event

type Parameters = ()

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

type Strategy = BoxedStrategy<Event>

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

fn arbitrary_with(args: <Self as Arbitrary>::Parameters) -> Self::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 Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Event

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Event

fn eq(&self, other: &Event) -> 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 Event

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Event

impl StructuralPartialEq for Event
