Enum MetricEventLoggerQuerierRequest

pub enum MetricEventLoggerQuerierRequest {
    WatchLogs {
        project_id: u32,
        method: LogMethod,
        responder: MetricEventLoggerQuerierWatchLogsResponder,
    },
    ResetLogger {
        project_id: u32,
        method: LogMethod,
        control_handle: MetricEventLoggerQuerierControlHandle,
    },
}

LoggerQuerier provides a way to query mock metrics services to check that clients of metrics are logging events as expected.

Variants

WatchLogs

Returns the first N events that were logged for the logger with the given project_id and a more flag indicating whether there were more than N events logged. There is no way to retrieve events logged after the first N events.

Will hang until at least one metrics metric is recorded for the given project_id and method.

Repeated calls to WatchLogs for a given LogMethod will block until new events are logged with that method, enabling tests to synchronize without sleeps or timeouts.

Fields

project_id: u32

method: LogMethod

responder: MetricEventLoggerQuerierWatchLogsResponder

ResetLogger

Clear all logged events by logging method for the logger with the given project_id.

This is a no-op if a logger for the given project_id does not exist. Notably, it does not create a new logger with project_id if one does not already exist.

Fields

project_id: u32

method: LogMethod

control_handle: MetricEventLoggerQuerierControlHandle
