}

Config for disabling builtin data sources in the tracing service.

Fields

disable_clock_snapshotting: Option<bool>

Disable emitting clock timestamps into the trace.

disable_trace_config: Option<bool>

Disable echoing the original trace config in the trace.

disable_system_info: Option<bool>

Disable emitting system info (build fingerprint, cpuinfo, etc).

disable_service_events: Option<bool>

Disable emitting events for data-source state changes (e.g. the marker for all data sources having ACKed the start of the trace).

primary_trace_clock: Option<i32>

The authoritative clock domain for the trace. Defaults to BOOTTIME. See also ClockSnapshot’s primary_trace_clock. The configured value is written into the trace as part of the ClockSnapshots emitted by the service. Trace processor will attempt to translate packet/event timestamps from various data sources (and their chosen clock domains) to this domain during import. Added in Android R.

snapshot_interval_ms: Option<u32>

Time interval in between snapshotting of sync markers, clock snapshots, stats, and other periodic service-emitted events. Note that the service only keeps track of the first and the most recent snapshot until ReadBuffers() is called.

prefer_suspend_clock_for_snapshot: Option<bool>

Hints to the service that a suspend-aware (i.e. counting time in suspend) clock should be used for periodic snapshots of service-emitted events. This means, if a snapshot should have happened during suspend, it will happen immediately after the device resumes.

Choosing a clock like this is done on best-effort basis; not all platforms (e.g. Windows) expose a clock which can be used for periodic tasks counting suspend. If such a clock is not available, the service falls back to the best-available alternative.

Introduced in Android S. TODO(lalitm): deprecate this in T and make this the default if nothing crashes in S.

disable_chunk_usage_histograms: Option<bool>

Disables the reporting of per-trace-writer histograms in TraceStats.

Trait Implementations

impl Clone for BuiltinDataSource

fn clone(&self) -> BuiltinDataSource

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BuiltinDataSource

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

Formats the value using the given formatter.

impl Default for BuiltinDataSource

fn default() -> Self

Returns the “default value” for a type.

impl Message for BuiltinDataSource

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

impl PartialEq for BuiltinDataSource

fn eq(&self, other: &BuiltinDataSource) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
