Struct PerfettoMetatrace

pub struct PerfettoMetatrace {
    pub event_duration_ns: Option<u64>,
    pub counter_value: Option<i32>,
    pub thread_id: Option<u32>,
    pub has_overruns: Option<bool>,
    pub args: Vec<Arg>,
    pub interned_strings: Vec<InternedString>,
    pub record_type: Option<RecordType>,
}

Used to trace the execution of perfetto itself.

Fields

event_duration_ns: Option<u64>

Only when using |event_id|.

counter_value: Option<i32>

Only when using |counter_id|.

thread_id: Option<u32>

ID of the thread that emitted the event.

has_overruns: Option<bool>

If true the meta-tracing ring buffer had overruns and hence some data is missing from this point.

args: Vec<Arg>

Args for the event.

interned_strings: Vec<InternedString>

record_type: Option<RecordType>

See base/metatrace_events.h for definitions.

Implementations

impl PerfettoMetatrace

pub fn event_duration_ns(&self) -> u64

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

pub fn counter_value(&self) -> i32

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

pub fn thread_id(&self) -> u32

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

pub fn has_overruns(&self) -> bool

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

Trait Implementations

impl Clone for PerfettoMetatrace

fn clone(&self) -> PerfettoMetatrace

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PerfettoMetatrace

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

Formats the value using the given formatter.

impl Default for PerfettoMetatrace

fn default() -> Self

Returns the “default value” for a type.

impl Message for PerfettoMetatrace

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,

Encodes the message to a newly allocated buffer.

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

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

impl PartialEq for PerfettoMetatrace

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