Enum InsertMessageOutcome 

pub enum InsertMessageOutcome {
    Inserted,
    Deduplicated {
        message_id: MessageId,
    },
}

What MailStore::insert_message did. Distinguishes a genuinely new message from a retry recognised by its idempotency key, so the engine can return the original mail4agent_api::SendResponse without needing a second read.

Variants

Inserted

The message was new and is now stored.

Deduplicated

A prior send from the same participant already used this idempotency key; nothing was created, and this is the id of that prior message.

Fields

message_id: MessageId
