Struct CommandEnvelope 

pub struct CommandEnvelope {
    pub aggregate_type: String,
    pub instance_id: String,
    pub command: Value,
    pub context: CommandContext,
}

A type-erased command envelope for cross-aggregate dispatch.

Produced by process managers when reacting to events. The command field is a serde_json::Value because the process manager does not know the concrete command type of the target aggregate at compile time. The dispatch layer deserializes it into the correct A::Command at runtime.

Fields

• aggregate_type - Target aggregate type name (must match Aggregate::AGGREGATE_TYPE).
• instance_id - Target aggregate instance identifier.
• command - JSON-serialized command payload.
• context - Cross-cutting metadata forwarded to the command handler.

Fields

aggregate_type: String

Target aggregate type name (must match Aggregate::AGGREGATE_TYPE).

instance_id: String

Target aggregate instance identifier.

command: Value

JSON-serialized command payload.

context: CommandContext

Cross-cutting metadata forwarded to the command handler.
