Struct MailRelayStore 

pub struct MailRelayStore { /* private fields */ }

Framework-neutral in-memory relay model, NOT a hosted or durable service. All outputs are owned copies. Save/restore snapshots atomically in a real service; enforce admission limits and serialized access outside this model. The short-lived Identity nonce cache is not part of the snapshot.

Implementations

impl MailRelayStore

pub fn new(origin: impl Into<String>) -> Result<Self>

pub fn with_limits( origin: impl Into<String>, max_packets: usize, max_bytes: usize, ) -> Result<Self>

Per-mailbox limits on retained packets.

pub fn origin(&self) -> &str

pub fn discovery(&self) -> Value

pub fn publish( &mut self, value: &Value, now: i64, ) -> Result<AcceptedRecord<MailboxCardPayload>>

pub fn publish_with_nonce_store<S: NonceStore + ?Sized>( &mut self, value: &Value, now: i64, nonces: &mut S, ) -> Result<AcceptedRecord<MailboxCardPayload>>

Inject the origin-wide Identity nonce store when several protocols share a service. All other checks precede nonce consumption.

pub fn card( &self, mailbox_id: &str, ) -> Result<AcceptedRecord<MailboxCardPayload>>

pub fn deliver( &mut self, mailbox_id: &str, packet: &Packet, now: i64, ) -> Result<DeliveryResult>

pub fn list( &self, mailbox: &str, jwt: &str, now: i64, limit: usize, cursor: Option<&str>, ) -> Result<ListResponse<PacketRecord>>

The cursor is the decimal seq of the last returned record.

pub fn delete( &mut self, mailbox: &str, id: &str, jwt: &str, now: i64, ) -> Result<()>

pub fn prune(&mut self, now: i64) -> Result<()>

Drop expired packets and tombstones, then forget mailboxes whose current card’s receive_until passed; a later card is a new registration.

pub fn snapshot(&self) -> Result<Value>

pub fn from_snapshot( value: &Value, max_packets: usize, max_bytes: usize, ) -> Result<Self>

Restore trusted local state saved by snapshot; limits are not part of it.
