Struct CallTree 

pub struct CallTree {
    pub nodes: Vec<CallTreeNode>,
    pub edges: Vec<CallTreeEdge>,
    pub truncated: bool,
}

A focus and every symbol it reaches inside the budgets. 一个焦点，以及它在预算内能到达的全部符号。

nodes[0] is always the focus; the rest follow in placement order, which is breadth-first over the hops, so a caller that owns a raw index also owns a stable cursor order. nodes[0] 始终是焦点；其余按放置顺序排列，即按跳数广度优先。因此持有裸下标的调用方 也就持有一份稳定的游标顺序。

Fields

nodes: Vec<CallTreeNode>

Placed nodes, focus first. 已放置的节点，焦点在首位。

edges: Vec<CallTreeEdge>

Every relation whose two ends are both placed. 两端都已放置的全部关系。

truncated: bool

Whether at least one symbol was dropped because the node budget ran out. 是否至少有一个符号因为节点预算用尽而被丢弃。

Implementations

impl CallTree

pub fn rows(&self) -> usize

Rows the drawing needs, i.e. the highest lane in use plus one. 绘制所需行数，即使用中的最大车道加一。

pub fn level_span(&self) -> (i32, i32)

Lowest and highest level in use, i.e. the columns the drawing needs. 使用中的最低与最高层，即绘制所需的列范围。

pub fn index_of(&self, symbol: &str) -> Option<usize>

Index of the placed node matching a symbol, as the kernel matches symbols elsewhere: a bare name matches a qualified path suffix. 匹配某个符号的节点下标；匹配规则与内核别处一致：裸名可匹配限定路径的后缀。

pub fn backward_edges(&self) -> usize

Forced edges, i.e. the relations the axis could not draw left to right. 反向边，即无法沿轴从左到右画出的那些关系。
