Struct MaskingStrategyEngine 

pub struct MaskingStrategyEngine { /* private fields */ }

脱敏策略引擎：管理多条字段规则，按优先级应用脱敏。

当多个规则匹配同一字段时，仅应用优先级最高（数值最小）的规则。 支持条件脱敏：仅在条件满足时才对字段应用脱敏。

Implementations

impl MaskingStrategyEngine

pub fn new() -> Self

创建空策略引擎

pub fn add_rule(self, rule: FieldMaskingRule) -> Self

添加字段规则（链式）

pub fn add_rules(self, rules: Vec<FieldMaskingRule>) -> Self

pub fn rule_count(&self) -> usize

规则数量

pub fn clear(&mut self)

清空规则

pub fn effective_rule( &self, field: &str, data: &HashMap<String, String>, ) -> Option<&MaskingRule>
