Struct TimePropertiesDS

pub struct TimePropertiesDS {
    pub current_utc_offset: Option<i16>,
    pub leap_indicator: LeapIndicator,
    pub time_traceable: bool,
    pub frequency_traceable: bool,
    pub ptp_timescale: bool,
    pub time_source: TimeSource,
}

A concrete implementation of the PTP Time Properties dataset

This dataset describes the timescale currently in use, as well as any upcoming leap seconds on that timescale.

For more details see IEEE1588-2019 section 8.2.4.

Fields

current_utc_offset: Option<i16>

The offset off UTC time compared to TAI time in seconds.

leap_indicator: LeapIndicator

Describes upcoming leap seconds.

time_traceable: bool

Wheter the timescale is tracable to a primary reference

frequency_traceable: bool

Wheter the frequence determining the timescale is tracable to a primary reference. True when the timescale is PTP, false when the timescale is ARB.

ptp_timescale: bool

Wheter the timescale of the Grandmaster PTP Instance is PTP.

time_source: TimeSource

The time source used by the Grandmaster PTP instance.

Implementations

impl TimePropertiesDS

pub fn new_ptp_time( current_utc_offset: Option<i16>, leap_indicator: LeapIndicator, time_traceable: bool, frequency_traceable: bool, time_source: TimeSource, ) -> Self

Create a Time Properties data set for the PTP timescale.

This creates a dataset for the default PTP timescale, which is UTC seconds since the PTP epoch excluding leap seconds. The traceability properties indicate whether the current clock time and frequency can be traced back to an internationally recognized standard in the metrology sense of the word. When in doubt, just set these to false.

pub fn new_arbitrary_time( time_traceable: bool, frequency_traceable: bool, time_source: TimeSource, ) -> Self

Create a Time Properties data set for an Arbitrary timescale

The arbitrary timescale can be used when wanting to synchronize multiple computers using PTP to a timescale that is unrelated to UTC. The traceability properties indicate whether the current clock time and frequency can be traced back to an internationally recognized standard in the metrology sense of the word. When in doubt, just set these to false.

pub fn is_ptp(&self) -> bool

Is this timescale a ptp (utc-derived) timescale?

pub fn leap_indicator(&self) -> LeapIndicator

Information on upcoming leap seconds

pub fn utc_offset(&self) -> Option<i16>

Current offset to UTC caused by leap seconds

Returns None if this time scale is not referenced to UTC

Trait Implementations

impl Clone for TimePropertiesDS

fn clone(&self) -> TimePropertiesDS

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimePropertiesDS

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

Formats the value using the given formatter.

impl Default for TimePropertiesDS

fn default() -> TimePropertiesDS

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TimePropertiesDS

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TimePropertiesDS

fn eq(&self, other: &TimePropertiesDS) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TimePropertiesDS

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
