Struct ClockQuality 

pub struct ClockQuality {
    pub clock_class: u8,
    pub clock_accuracy: ClockAccuracy,
    pub offset_scaled_log_variance: u16,
}

A description of the accuracy and type of a clock.

Fields

clock_class: u8

The PTP clock class.

Per the standard, 248 is the default, and a good option for most use cases. For grandmaster clocks, this should be below 128 to ensure the clock never takes time from another source. A value of 6 is a good option for a node with an external time source.

For other potential values, see IEEE1588-2019 section 7.6.2.5.

clock_accuracy: ClockAccuracy

The accuracy of the clock

offset_scaled_log_variance: u16

2-log of the variance (in seconds^2) of the clock when not synchronized.

See IEEE1588-2019 section 7.6.3.5 for more details.

Implementations

impl ClockQuality

pub fn serialize(self, buffer: &mut [u8]) -> Result<(), Error>

Serialize a clock quality to a buffer of 4 bytes.

Errors

Fails when the provided buffer is too short.

pub fn deserialize(buffer: &[u8]) -> Result<Self, Error>

Deserialize a clock quality from a buffer of 4 bytes.

Errors

Fails when the provided buffer is too short.
