Implementations

impl RecorderSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<RecorderEvent, 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 start_logging( &self, client_id: &str, metrics: &[Metric], duration_ms: u32, output_samples_to_syslog: bool, output_stats_to_syslog: bool, ___deadline: MonotonicInstant, ) -> Result<RecorderStartLoggingResult, Error>

Initiates logging of specified metrics for the provided duration. Supports concurrent logging of different metrics. Logging may be terminated early with a call to StopLogging.

This call will fail if logging of the specified metric is already active. For this reason, a client may wish to precede a StartLogging call with a StopLogging call, after which the only reason for The logger to be active would be a conflict with another client.

• request client_id String format Id of the client. Client may choose any Id with a maximum byte size of 8 (e.g., “ffxTest”).
• request metrics Type of the metrics to be polled and logged.
• request duration_ms Duration of logging in milliseconds. After this duration, polling and logging will cease.
• request output_samples_to_syslog Toggle for outputting raw data to syslog.
• request output_stats_to_syslog Toggle for outputting any available statistics to syslog.
• error a [fuchsia.metrics.test/MeticsLoggerError] value indicating why the request failed.

pub fn start_logging_forever( &self, client_id: &str, metrics: &[Metric], output_samples_to_syslog: bool, output_stats_to_syslog: bool, ___deadline: MonotonicInstant, ) -> Result<RecorderStartLoggingForeverResult, Error>

Initiates logging of specified metrics. Supports concurrent logging of different metrics. Logging will only end upon a StopLogging call.

StartLogging should be preferred for usage in automated tests to ensure that logging terminates even if the test crashes.

• request client_id String format Id of the client. Client may choose any Id with a maximum byte size of 8 (e.g., “ffxTest”).
• request metrics Type of the metrics to be polled and logged.
• request output_samples_to_syslog Toggle for outputting raw data to syslog.
• request output_stats_to_syslog Toggle for outputting any available statistics to syslog.
• error a [fuchsia.metrics.test/RecorderError] value indicating why the request failed.

pub fn stop_logging( &self, client_id: &str, ___deadline: MonotonicInstant, ) -> Result<bool, Error>

Terminates all active logging tasks with the given client_id. It is valid to call this method when logging is inactive.

• request client_id String format Id of the client.

• response status A bool value indicating if existing logging was stopped (true) or there’sno existing logging for the client.
