Struct Event 

pub struct Event {
    pub id: CorrelationId,
    pub timestamp: Timestamp,
    pub event_type: EventType,
    pub payload: Vec<u8>,
    pub source_did: Did,
    pub signature: Signature,
}

A signed, timestamped event in the EXOCHAIN system.

Fields

id: CorrelationId

Unique identifier for this event.

timestamp: Timestamp

HLC timestamp of when the event was created.

event_type: EventType

Classification of the event.

payload: Vec<u8>

CBOR-encoded payload (opaque bytes).

source_did: Did

DID of the entity that produced the event.

signature: Signature

Ed25519 signature over the canonical event content.

Implementations

impl Event

pub fn write_signable_bytes<W: Write>(&self, writer: W) -> Result<()>

Construct the canonical bytes that are signed.

The signed content is a domain-separated, schema-versioned CBOR envelope over id, timestamp, event_type, payload, and source_did.

Errors

Returns ExoError::SerializationError if CBOR encoding fails.

pub fn signable_bytes(&self) -> Result<Vec<u8>>

Construct the canonical bytes that are signed.

The signed content is: id || timestamp || event_type || payload || source_did serialized as CBOR.

Errors

Returns ExoError::SerializationError if CBOR encoding fails.

Trait Implementations

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 Eq for Event

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.
