Struct ThreadDescriptor

pub struct ThreadDescriptor {
    pub pid: Option<i32>,
    pub tid: Option<i32>,
    pub thread_name: Option<String>,
    pub chrome_thread_type: Option<i32>,
    pub reference_timestamp_us: Option<i64>,
    pub reference_thread_time_us: Option<i64>,
    pub reference_thread_instruction_count: Option<i64>,
    pub legacy_sort_index: Option<i32>,
}

Describes a thread’s attributes. Emitted as part of a TrackDescriptor, usually by the thread’s trace writer.

Next id: 9.

Fields

pid: Option<i32>

tid: Option<i32>

thread_name: Option<String>

chrome_thread_type: Option<i32>

reference_timestamp_us: Option<i64>

Deprecated. Use ClockSnapshot in combination with TracePacket’s timestamp and timestamp_clock_id fields instead.

reference_thread_time_us: Option<i64>

Absolute reference values. Clock values in subsequent TrackEvents can be encoded accumulatively and relative to these. This reduces their var-int encoding size. TODO(eseckler): Deprecated. Replace these with ClockSnapshot encoding.

reference_thread_instruction_count: Option<i64>

legacy_sort_index: Option<i32>

To support old UI. New UI should determine default sorting by thread_type.

Implementations

impl ThreadDescriptor

pub fn pid(&self) -> i32

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

pub fn tid(&self) -> i32

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

pub fn legacy_sort_index(&self) -> i32

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

pub fn chrome_thread_type(&self) -> ChromeThreadType

Returns the enum value of chrome_thread_type, or the default if the field is unset or set to an invalid enum value.

pub fn set_chrome_thread_type(&mut self, value: ChromeThreadType)

Sets chrome_thread_type to the provided enum value.

pub fn thread_name(&self) -> &str

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

pub fn reference_timestamp_us(&self) -> i64

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

pub fn reference_thread_time_us(&self) -> i64

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

pub fn reference_thread_instruction_count(&self) -> i64

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

Trait Implementations

impl Clone for ThreadDescriptor

fn clone(&self) -> ThreadDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadDescriptor

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

Formats the value using the given formatter.

impl Default for ThreadDescriptor

fn default() -> Self

Returns the “default value” for a type.

impl Message for ThreadDescriptor

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,

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

impl PartialEq for ThreadDescriptor

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