Implementations

impl MetricEventLoggerQuerierSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: Time ) -> Result<MetricEventLoggerQuerierEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn watch_logs( &self, project_id: u32, method: LogMethod, ___deadline: Time ) -> Result<(Vec<MetricEvent>, bool), Error>

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.

pub fn reset_logger( &self, project_id: u32, method: LogMethod ) -> Result<(), Error>

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.

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

Formats the value using the given formatter.
