Struct TreeMetrics 

pub struct TreeMetrics {
    pub nodes: u64,
    pub decisions: u64,
    pub max_depth: u32,
}

一个根（通常是方法体）的结构指标。

Fields

nodes: u64

子树节点总数（从根可达的 arena 节点；不含编辑残留的游离节点）。

decisions: u64

判定点数：if / while / do / for / foreach / case / catch / 三元 / && / ||（McCabe 复杂度的决策点部分）。

max_depth: u32

最大嵌套深度（语句容器嵌套层数；反编译嵌套块与扁平化状态机 的直接体现）。
