Struct TraceEvent 

Source 
pub struct TraceEvent {
    pub node: u32,
    pub phase: TracePhase,
    pub tid: u32,
    pub start_us: i64,
    pub dur_us: i64,
    pub input_ts: i64,
}
Expand description

一条执行 span。时间均相对图 epoch,单位微秒。

Fields§

§node: u32

节点索引(导出时解析成节点名/算子名)。

§phase: TracePhase§tid: u32

该图内稳定分配的小整数线程号(chrome 的泳道 tid)。

§start_us: i64

相对图 epoch 的起始微秒。

§dur_us: i64

本次回调时长(微秒)。

§input_ts: i64

本次激活的对齐时间戳原值。Open 阶段是 Unstarted、Close 阶段是 Done,都不是流内 值 —— 导出时按名字记(见 to_chrome_trace_json),不然会是贴着 i64::MIN/MAX 的数。
