Struct DateTime 

pub struct DateTime { /* private fields */ }

A date/time value. This is a wrapper around the chrono type with extra functionality for obtaining ticks in OPC UA measurements, endtimes, epoch etc.

Trait Implementations

impl Add<TimeDelta> for DateTime

type Output = DateTime

The resulting type after applying the + operator.

fn add(self, duration: TimeDelta) -> DateTime

Performs the + operation.

impl BinaryDecodable for DateTime

fn decode<S>(stream: &mut S, ctx: &Context<'_>) -> Result<DateTime, Error>

where S: Read + ?Sized,

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.

impl BinaryEncodable for DateTime

DateTime encoded as 64-bit signed int

fn byte_len(&self, _ctx: &Context<'_>) -> 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.

fn encode<S>(&self, stream: &mut S, _ctx: &Context<'_>) -> Result<(), Error>

where S: Write + ?Sized,

Encodes the instance to the write stream.

fn override_encoding(&self) -> Option<BuiltInDataEncoding>

Override the extension object encoding used for this type. This only makes sense if the type can only ever be encoded using a single built-in encoding.

fn encode_to_vec(&self, ctx: &Context<'_>) -> Vec<u8>

Convenience method for encoding a message straight into an array of bytes. It is preferable to reuse buffers than to call this so it should be reserved for tests and trivial code.

impl Clone for DateTime

fn clone(&self) -> DateTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DateTime

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

Formats the value using the given formatter.

impl Default for DateTime

fn default() -> DateTime

Returns the “default value” for a type.

impl Display for DateTime

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

Formats the value using the given formatter.

Converts to this type from the input type.

impl From<DateTime> for DataValue

fn from(v: DateTime) -> DataValue

Converts to this type from the input type.

impl From<DateTime> for DateTime<Utc>

fn from(value: DateTime) -> DateTime<Utc>

Converts to this type from the input type.

impl From<i64> for DateTime

fn from(value: i64) -> DateTime

Converts to this type from the input type.

impl FromStr for DateTime
