Struct MessageSummary 

pub struct MessageSummary {
    pub id: MessageId,
    pub sender_id: AgentId,
    pub sender_name: AgentName,
    pub recipient_id: Option<AgentId>,
    pub encryption: MessageEncryption,
    pub body: Option<String>,
    pub sent_at: DateTime<Utc>,
    pub read_at: Option<DateTime<Utc>>,
    pub state: Option<InboxState>,
    pub ciphertext: Option<String>,
    pub wrapped_key: Option<String>,
    pub sender_public_key: Option<String>,
}

One message as rendered in an inbox.

recipient_id is None for broadcasts. body is None when the server cannot produce plaintext (E2EE rows, phase 2) — clients decrypt those locally from the ciphertext fields that phase 2 adds.

Fields

id: MessageId

sender_id: AgentId

sender_name: AgentName

recipient_id: Option<AgentId>

None = system broadcast (delivered to every agent).

encryption: MessageEncryption

body: Option<String>

Plaintext body (server-mode and broadcasts). None for E2EE.

sent_at: DateTime<Utc>

read_at: Option<DateTime<Utc>>

When this agent read the message. None = unread, for a DM; a broadcast has none (its reads are one watermark per agent), so read its state.

state: Option<InboxState>

Where this message stands for this read, by the rule the inbox’s unread count uses (0.117.1). Absent from servers before it, when read_at is all there is to go on.

ciphertext: Option<String>

E2EE only: hex envelope blob (version || xnonce || ct).

wrapped_key: Option<String>

E2EE only: hex message key wrapped to this agent’s X25519 key (the recipient wrap for inbox rows, the sender wrap for outbox export).

sender_public_key: Option<String>

E2EE only: the sender’s hex Ed25519 public key, for verifying the embedded message signature. TOFU: pin it — a key change for a known sender is a red flag, not a routine event.

Implementations

impl MessageSummary

pub fn state_or_read_at(&self) -> InboxState

Self::state, or for a server that does not send it, what read_at says

pub fn decrypt( &self, own_secret: &EncryptionSecretKey, ) -> Option<Result<String, EnvelopeError>>

Decrypt and verify an E2EE message with this agent’s encryption secret. Returns the plaintext, or None if this is not an E2EE row (use body directly).

Verification uses the row’s own context fields and sender_public_key — callers doing TOFU pinning should check the key against their pin first.

Trait Implementations

impl Clone for MessageSummary

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageSummary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageSummary

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for MessageSummary

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
