Struct TraceFrame 

pub struct TraceFrame {
    pub frame_id: u64,
    pub parent: Option<u64>,
    pub node: NodeId,
    pub function: &'static str,
    pub source: Option<SourceLocation>,
}

One recorded frame, flattened for text. 一个已记录调用帧的文本平铺形式。

function and source are interned while a document is parsed, so repeated frames share one string per distinct name instead of leaking one per record. function 与 source 在解析文档时被驻留，因此重复帧对每个不同名字只共享一个字符串， 而不是每条记录泄漏一个。

Fields

frame_id: u64

The trace-local frame id. 追踪内的帧 id。

parent: Option<u64>

The enclosing frame id, None for a root frame. 外层调用帧 id；根帧为 None。

node: NodeId

The registry node the frame belongs to. 该帧所属的注册机节点。

function: &'static str

The logical function active in the frame. 该帧中处于活动状态的逻辑函数名。

source: Option<SourceLocation>

The callsite that entered the frame, when one is known. 进入该帧的调用点（若可知）。
