Struct CommandEnvelope 

pub struct CommandEnvelope {

    pub command_id: CommandId,
    pub project_id: ProjectId,
    pub command_type: String,
    pub schema_version: u32,
    pub issued_at: Timestamp,
    pub actor: Actor,
    pub origin: Origin,
    pub target_aggregate_type: Option<String>,
    pub target_aggregate_id: Option<AggregateId>,
    pub expected_version: Option<u32>,
    pub idempotency_key: IdempotencyKey,
    pub causation_id: Option<EventId>,
    pub correlation_id: Option<CorrelationId>,
    pub payload: Value,
}

One issued command. Commands are requests — only the events they cause are truth. idempotency_key is required: reissuing the same key is a no-op.

Fields

command_id: CommandId

project_id: ProjectId

command_type: String

OPEN bounded string naming the command (e.g. cancel_attempt).

schema_version: u32

issued_at: Timestamp

actor: Actor

origin: Origin

target_aggregate_type: Option<String>

target_aggregate_id: Option<AggregateId>

expected_version: Option<u32>

CAS precondition: the target aggregate’s current version.

idempotency_key: IdempotencyKey

causation_id: Option<EventId>

correlation_id: Option<CorrelationId>

payload: Value
