}

Asynchronously delivered server data.

Each variant models a distinct class of server notification. The driver task converts raw UntaggedResponses into TypedEvents and publishes them via DriverEventSink.

Variants

Alert(String)

RFC 3501 §7.1 [ALERT] — informational, never dropped.

Bye

RFC 3501 §7.1.5 BYE — connection ending.

Fields

code: Option<ResponseCode>

text: String

NotificationOverflow

RFC 5465 §5.8 NOTIFICATIONOVERFLOW — NOTIFY registration cleared.

Fields

code: Option<String>

text: String

QueueOverflow

Internal overflow marker. Emitted when the event queue drops events.

Fields

dropped_count: usize

since: Instant

Exists(u32)

RFC 3501 §7.3.1 EXISTS — mailbox size change.

Recent(u32)

Vanished

RFC 7162 VANISHED — message removed (UID form).

Fields

earlier: bool

uids: Vec<UidRange>

FetchUpdate(Box<FetchResponse>)

RFC 3501 §7.4.2 FETCH — flags or other update.

MailboxEvent(MailboxInfo)

RFC 5465 §5 MailboxName event.

MetadataChange

RFC 5465 §5 MailboxMetadataChange.

ServerMetadataChange

RFC 5465 §5 ServerMetadataChange.

RFC 3501 §7.2.1 CAPABILITY change.

Extension(Box<UntaggedResponse>)

Extension or future event.

Trait Implementations

impl Clone for TypedEvent

fn clone(&self) -> TypedEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypedEvent

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

Formats the value using the given formatter.

impl From<UntaggedResponse> for TypedEvent

fn from(resp: UntaggedResponse) -> Self

Convert a raw untagged response into a typed event.

Used by the driver task when routing unsolicited responses to the event sink. Handles the well-known response variants directly; everything else is wrapped in TypedEvent::Extension.
