Data type ID 23

Fields

value: Option<Variant>

The value. BaseDataType Not present if the Value bit in the EncodingMask is False.

status: Option<StatusCode>

The status associated with the value. Not present if the StatusCode bit in the EncodingMask is False

source_timestamp: Option<DateTime>

The source timestamp associated with the value. Not present if the SourceTimestamp bit in the EncodingMask is False.

source_picoseconds: Option<Int16>

The number of 10 picosecond intervals for the SourceTimestamp. Not present if the SourcePicoSeconds bit in the EncodingMask is False. If the source timestamp is missing the picoseconds are ignored.

server_timestamp: Option<DateTime>

The Server timestamp associated with the value. Not present if the ServerTimestamp bit in the EncodingMask is False.

server_picoseconds: Option<Int16>

The number of 10 picosecond intervals for the ServerTimestamp. Not present if the ServerPicoSeconds bit in the EncodingMask is False. If the Server timestamp is missing the picoseconds are ignored.

Methods

    T: 'static + Into<Variant>, 

fn null() -> DataValue

Trait Implementations

impl Debug for DataValue

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for DataValue

fn clone(&self) -> DataValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for DataValue

fn eq(&self, __arg_0: &DataValue) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &DataValue) -> bool

This method tests for !=.

impl BinaryEncoder<DataValue> for DataValue

fn byte_len(&self) -> usize

Returns the byte length of the structure. This calculation should be exact and as efficient as possible.

fn encode<S: Write>(&self, stream: &mut S) -> EncodingResult<usize>

Encodes the instance to the write stream.

fn decode<S: Read>(stream: &mut S) -> EncodingResult<Self>

Decodes an instance from the read stream.
