Struct cqrs_es2::EventContext

pub struct EventContext<C: ICommand, E: IEvent> {
    pub aggregate_id: String,
    pub sequence: i64,
    pub payload: E,
    pub metadata: HashMap<String, String>,
    // some fields omitted
}

EventContext is a data structure that encapsulates an event with along with it’s pertinent information. All of the associated data will be transported and persisted together.

Within any system an event must be unique based on its’ aggregate_type, aggregate_id and sequence.

Fields

aggregate_id: String

The id of the aggregate instance.

sequence: i64

The sequence number for an aggregate instance.

payload: E

The event payload with all business information.

metadata: HashMap<String, String>

Additional metadata for use in auditing, logging or debugging purposes.

Implementations

impl<C: ICommand, E: IEvent> EventContext<C, E>

pub fn new(
    aggregate_id: String,
    sequence: i64,
    payload: E,
    metadata: HashMap<String, String>
) -> Self

Constructor

Trait Implementations

impl<C: Clone + ICommand, E: Clone + IEvent> Clone for EventContext<C, E>

fn clone(&self) -> EventContext<C, E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C: Debug + ICommand, E: Debug + IEvent> Debug for EventContext<C, E>

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

Formats the value using the given formatter.

impl<C: PartialEq + ICommand, E: PartialEq + IEvent> PartialEq<EventContext<C, E>> for EventContext<C, E>

fn eq(&self, other: &EventContext<C, E>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &EventContext<C, E>) -> bool

This method tests for !=.
