Struct PerfettoTraceBuilder 

pub struct PerfettoTraceBuilder { /* private fields */ }

State for a trace builder instance.

Implementations

impl PerfettoTraceBuilder

pub fn new() -> Self

Create a Perfetto trace builder.

Each trace builder instance will use a unique TrustedPacketSequenceId when creating packets.

pub fn build_enter_exit_track_descriptor_trace_packet( &mut self, current_time_ns: u64, id: Id, parent: Id, name: &str, ) -> TracePacket

Build a TracePacket containing the TrackDescriptor for crate::tracker::Track::enter and crate::tracker::Track::exit events (using an incremental counter).

pub fn build_value_track_descriptor_trace_packet( &mut self, current_time_ns: u64, id: Id, parent: Id, name: &str, ) -> TracePacket

Build a TracePacket containing the TrackDescriptor for a sequence of crate::tracker::Track::values.

pub fn build_activity_track_descriptor_trace_packet( &mut self, current_time_ns: u64, id: Id, parent: Id, name: &str, ) -> TracePacket

Build a TracePacket containing the TrackDescriptor for activity slices denoted by crate::tracker::Track::begin_activity and crate::tracker::Track::end_activity events.

pub fn build_enter_track_event_trace_packet( &self, current_time_ns: u64, id: Id, other: Id, ) -> TracePacket

Build a TracePacket containing a TrackEvent to represent an crate::tracker::Track::enter event (as an incremental counter update).

pub fn build_exit_track_event_trace_packet( &self, current_time_ns: u64, id: Id, other: Id, ) -> TracePacket

Build a TracePacket containing a TrackEvent to represent an crate::tracker::Track::exit event (as an incremental counter update).

pub fn build_value_track_event_trace_packet( &self, current_time_ns: u64, id: Id, value: f64, ) -> TracePacket

Build a TracePacket containing the TrackEvent for a floating point crate::tracker::Track::value.

pub fn build_activity_begin_trace_packet( &self, current_time_ns: u64, id: Id, name: &str, correlation_id: Option<u64>, ) -> TracePacket

Build a TracePacket containing the TrackEvent for a crate::tracker::Track::begin_activity SliceBegin event.

pub fn build_activity_end_trace_packet( &self, current_time_ns: u64, id: Id, ) -> TracePacket

Build a TracePacket containing the TrackEvent for a crate::tracker::Track::end_activity SliceEnd event.

pub fn build_trace_to_bytes(&self, trace_packets: Vec<TracePacket>) -> Vec<u8>

Build a Trace message containing the passed TracePackets and serialise it to unsigned bytes.
