Expand description

Trait for messages that belong to a specific business domain.

This trait is automatically implemented by the #[derive(RingMessage)] macro when a domain attribute is specified.

§Example

#[derive(RingMessage)]
#[ring_message(type_id = 1, domain = "OrderMatching")]
pub struct SubmitOrder {
    #[message(id)]
    id: MessageId,
    symbol: String,
}

// Auto-generated:
impl DomainMessage for SubmitOrder {
    fn domain() -> Domain { Domain::OrderMatching }
}
