Struct SyncEvent 

pub struct SyncEvent {
    pub id: Uuid,
    pub sequence: u64,
    pub event_type: String,
    pub entity_type: String,
    pub entity_id: String,
    pub payload: Value,
    pub hash: String,
    pub signature: Option<String>,
    pub timestamp: DateTime<Utc>,
}

A sync event representing a state change in the system.

This is the Rust equivalent of the JS OutboxEvent and the VES v1.0 event envelope. Events are immutable once created.

Examples

use stateset_sync::SyncEvent;
use serde_json::json;

let event = SyncEvent::new(
    "order.created",
    "order",
    "ORD-123",
    json!({"total": 99.99}),
);
assert_eq!(event.event_type, "order.created");
assert_eq!(event.entity_type, "order");
assert!(!event.hash.is_empty());

Fields

id: Uuid

Unique event identifier.

sequence: u64

Monotonically increasing sequence number (0 = unassigned).

event_type: String

The type of event (e.g. order.created, inventory.adjusted).

entity_type: String

The entity type this event applies to (e.g. order, customer).

entity_id: String

The identifier of the entity.

payload: Value

The event payload as a JSON value.

hash: String

SHA-256 hash of the canonicalized payload (hex-encoded).

signature: Option<String>

Optional cryptographic signature (hex-encoded Ed25519).

timestamp: DateTime<Utc>

Timestamp when the event was created.

Implementations

impl SyncEvent

pub fn new( event_type: impl Into<String>, entity_type: impl Into<String>, entity_id: impl Into<String>, payload: Value, ) -> Self

Create a new SyncEvent with an auto-generated id, hash, and timestamp.

pub fn with_id( id: Uuid, sequence: u64, event_type: impl Into<String>, entity_type: impl Into<String>, entity_id: impl Into<String>, payload: Value, timestamp: DateTime<Utc>, ) -> Self

Create a SyncEvent with an explicit id and sequence.

pub fn compute_hash(payload: &Value) -> String

Compute the SHA-256 hash of a JSON payload, hex-encoded.

pub const fn with_sequence(self, sequence: u64) -> Self

Assign a sequence number to this event, returning a new event.

pub fn with_signature(self, signature: impl Into<String>) -> Self

Set the signature on this event.

Trait Implementations

impl Clone for SyncEvent

fn clone(&self) -> SyncEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SyncEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for SyncEvent

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SyncEvent

fn eq(&self, other: &SyncEvent) -> 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 PartialOrd for SyncEvent

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SyncEvent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
