Enum LatestEventValue 

pub enum LatestEventValue {
    None,
    Remote(TimelineEvent),
    LocalIsSending(LocalLatestEventValue),
    LocalHasBeenSent {
        event_id: OwnedEventId,
        value: LocalLatestEventValue,
    },
    LocalCannotBeSent(LocalLatestEventValue),
}

A latest event value!

Variants

None

No value has been computed yet, or no candidate value was found.

Remote(TimelineEvent)

The latest event represents a remote event.

LocalIsSending(LocalLatestEventValue)

The latest event represents a local event that is sending.

LocalHasBeenSent

The latest event represents a local event that has been sent successfully. It should come quickly as a Self::Remote.

Fields

event_id: OwnedEventId

ID of the sent event.

value: LocalLatestEventValue

Value, as for other Self::Local* variants.

LocalCannotBeSent(LocalLatestEventValue)

The latest event represents a local event that cannot be sent, either because a previous local event, or this local event cannot be sent.

Implementations

impl LatestEventValue

pub fn timestamp(&self) -> Option<MilliSecondsSinceUnixEpoch>

Get the timestamp of the LatestEventValue.

If it’s None, it returns None. If it’s Remote, it returns the TimelineEvent::timestamp. If it’s LocalIsSending, LocalHasBeenSent or LocalCannotBeSent, it returns the LocalLatestEventValue::timestamp value.

pub fn is_local(&self) -> bool

Check whether the LatestEventValue represents a local value or not, i.e. it is LocalIsSending or LocalCannotBeSent.

pub fn is_unsent(&self) -> bool

Check whether the LatestEventValue represents an unsent event, i.e. is LocalIsSending nor LocalCannotBeSent.

pub fn is_none(&self) -> bool

Check whether the LatestEventValue is not set, i.e. None.

pub fn event_id(&self) -> Option<OwnedEventId>

Get the event ID (if it exists) of the event representing the LatestEventValue.
