Implementations
sourceimpl NotificationMessage
impl NotificationMessage
sourcepub fn data_change(
sequence_number: u32,
publish_time: DateTime,
data_change_notifications: Vec<MonitoredItemNotification, Global>,
event_notifications: Vec<EventFieldList, Global>
) -> NotificationMessage
pub fn data_change(
sequence_number: u32,
publish_time: DateTime,
data_change_notifications: Vec<MonitoredItemNotification, Global>,
event_notifications: Vec<EventFieldList, Global>
) -> NotificationMessage
Create a notification message which contains data change AND / OR events. Calling this with neither will panic. Notification data can have up to 2 elements to covers the case in table 158 where a subscription contains monitored items for events and data.
sourcepub fn status_change(
sequence_number: u32,
publish_time: DateTime,
status: StatusCode
) -> NotificationMessage
pub fn status_change(
sequence_number: u32,
publish_time: DateTime,
status: StatusCode
) -> NotificationMessage
Create a status change notification message
sourcepub fn keep_alive(
sequence_number: u32,
publish_time: DateTime
) -> NotificationMessage
pub fn keep_alive(
sequence_number: u32,
publish_time: DateTime
) -> NotificationMessage
Create a keep-alive notification message
sourcepub fn notifications(
&self,
decoding_options: &DecodingOptions
) -> Option<(Vec<DataChangeNotification, Global>, Vec<EventNotificationList, Global>)>
pub fn notifications(
&self,
decoding_options: &DecodingOptions
) -> Option<(Vec<DataChangeNotification, Global>, Vec<EventNotificationList, Global>)>
Extract notifications from the message. Unrecognized / unparseable notifications will be
ignored. If there are no notifications, the function will return None
.
Trait Implementations
sourceimpl BinaryEncoder<NotificationMessage> for NotificationMessage
impl BinaryEncoder<NotificationMessage> for NotificationMessage
sourcefn byte_len(&self) -> usize
fn byte_len(&self) -> usize
Returns the exact byte length of the structure as it would be if encode
were called.
This may be called prior to writing to ensure the correct amount of space is available. Read more
sourcefn encode<S>(&self, stream: &mut S) -> Result<usize, StatusCode> where
S: Write,
fn encode<S>(&self, stream: &mut S) -> Result<usize, StatusCode> where
S: Write,
Encodes the instance to the write stream.
sourcefn decode<S>(
stream: &mut S,
decoding_options: &DecodingOptions
) -> Result<NotificationMessage, StatusCode> where
S: Read,
fn decode<S>(
stream: &mut S,
decoding_options: &DecodingOptions
) -> Result<NotificationMessage, StatusCode> where
S: Read,
Decodes an instance from the read stream. The decoding options contains restrictions set by
the server / client on the length of strings, arrays etc. If these limits are exceeded the
implementation should return with a BadDecodingError
as soon as possible. Read more
