Struct Score 

pub struct Score {
    pub value: f64,
    pub label: Option<String>,
}

评测分数(0.0–1.0,1.0 为最佳)

Fields

value: f64

分数值(0.0–1.0)

label: Option<String>

可选的分数标签

Implementations

impl Score

pub fn new(value: f64) -> Self

构造 0.0–1.0 之间的分数。

P2-8: Rust 的 f64::clamp(0.0, 1.0) 对 NaN 返回 NaN,会污染 summary 均值/标准差。这里先做 NaN 前置检查,按 0.0 处理(负无穷、 正无穷交给 clamp 收敛到边界)。

pub fn with_label(self, label: impl Into<String>) -> Self

附加分数标签(builder 风格)。
