Struct TracePacketDefaults 

pub struct TracePacketDefaults {
    pub timestamp_clock_id: Option<u32>,
    pub track_event_defaults: Option<TrackEventDefaults>,
    pub perf_sample_defaults: Option<PerfSampleDefaults>,
    pub v8_code_defaults: Option<V8CodeDefaults>,
}

Default values for TracePacket fields that hold for a particular TraceWriter packet sequence. This message contains a subset of the TracePacket fields with matching IDs. When provided, these fields define the default values that should be applied, at import time, to all TracePacket(s) with the same |trusted_packet_sequence_id|, unless otherwise specified in each packet.

Should be reemitted whenever incremental state is cleared on the sequence.

Fields

timestamp_clock_id: Option<u32>

track_event_defaults: Option<TrackEventDefaults>

Default values for TrackEvents (e.g. default track).

perf_sample_defaults: Option<PerfSampleDefaults>

Defaults for perf profiler packets (PerfSample).

v8_code_defaults: Option<V8CodeDefaults>

Defaults for V8 code packets (V8JsCode, V8InternalCode, V8WasmCode, V8RegexpCode)

Implementations

impl TracePacketDefaults

pub fn timestamp_clock_id(&self) -> u32

Returns the value of timestamp_clock_id, or the default value if timestamp_clock_id is unset.

Trait Implementations

impl Clone for TracePacketDefaults

fn clone(&self) -> TracePacketDefaults

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TracePacketDefaults

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

Formats the value using the given formatter.

impl Default for TracePacketDefaults

fn default() -> TracePacketDefaults

Returns the “default value” for a type.

impl Message for TracePacketDefaults

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for TracePacketDefaults

fn eq(&self, other: &TracePacketDefaults) -> 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.
