Struct CommandEnvelope 

pub struct CommandEnvelope {
    pub command_name: CommandName,
    pub command_id: String,
    pub app_id: AppId,
    pub node_id: NodeId,
    pub issued_at_ms: u64,
    pub idempotency_key: Option<String>,

Immutable command envelope.

Fields

command_name: CommandName

Stable command name.

command_id: String

Unique command identity.

app_id: AppId

Application issuing the command.

node_id: NodeId

Node issuing the command.

issued_at_ms: u64

Issue timestamp in Unix milliseconds.

idempotency_key: Option<String>

Optional key used to deduplicate mutating commands.

payload: Vec<u8>

Opaque application-owned payload.

trace: Option<TraceContext>

Optional distributed trace context.
