Struct CallTreeNode 

pub struct CallTreeNode {
    pub symbol: String,
    pub level: i32,
    pub lane: usize,
    pub parent: Option<usize>,
    pub cut_callers: usize,
    pub cut_callees: usize,
}

One placed symbol in the call tree. 调用树中已放置的一个符号。

Fields

symbol: String

Symbol label, spelled the way it was first seen. 符号标签，按首次见到的写法保留。

level: i32

Signed hop from the focus: negative upstream, zero the focus, positive downstream. 相对焦点的带符号跳数：负为上游，零为焦点，正为下游。

lane: usize

Row inside this node’s column. Two nodes never share one. 本节点所在列内的行号。同一列内两个节点绝不共用一行。

parent: Option<usize>

Index of the node that placed this one; None for the focus. 放置本节点的节点下标；焦点为 None。

cut_callers: usize

Distinct callers pointing at this node that the tree did not draw, because they were past the hop budget or the node budget ran out. 指向本节点、但树中没有画出的调用者个数（已去重），原因是超出跳数预算或节点预算用尽。

cut_callees: usize

Distinct callees of this node that the tree did not draw. 本节点调用、但树中没有画出的被调用者个数（已去重）。
