Enum PullSourceRequest

pub enum PullSourceRequest {
    UpdateDeviceProperties {
        properties: Properties,
        control_handle: PullSourceControlHandle,
    },
    Sample {
        urgency: Urgency,
        responder: PullSourceSampleResponder,
    },
    NextPossibleSampleTime {
        responder: PullSourceNextPossibleSampleTimeResponder,
    },
}

A protocol for time sources that produce time samples on demand.

Variants

UpdateDeviceProperties

Notifies the time source of changes to global properties of the device that it may use to increase accuracy of time measurements.

Fields

properties: Properties

control_handle: PullSourceControlHandle

Sample

Produce a new time sample.

The server may consider the supplied urgency and will potentially produce a sample more quickly but with lower accuracy when a request is marked urgent.

The server will return an error for permanent errors but will block on conditions that are not known to be permanent (e.g. network not connected).

The server will return a RATE_LIMITED error if the client should wait before requesting another sample. In this case the client may call NextPossibleSampleTime to determine when the time source will be willing to produce another sample.

Fields

urgency: Urgency

responder: PullSourceSampleResponder

NextPossibleSampleTime

Returns the monotonic time at which the PullSource is willing to produce another sample. If the PullSource is not rate limited it will return a time less than or equal to current monotonic time.

Fields

responder: PullSourceNextPossibleSampleTimeResponder
