ThreadDescriptor

Struct ThreadDescriptor 

Source
pub struct ThreadDescriptor {
    pub pid: Option<i32>,
    pub tid: Option<i64>,
    pub thread_name: Option<String>,
    pub chrome_thread_type: Option<i32>,

}
Expand description

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<i64>§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.
