Struct FieldMaskingRule 

pub struct FieldMaskingRule { /* private fields */ }

字段级脱敏规则：字段名 + 脱敏规则 + 可选条件 + 优先级。

优先级数值越小越先应用（默认 100）。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。

Implementations

impl FieldMaskingRule

pub fn new(field: &str, rule: MaskingRule) -> Self

创建无条件字段规则（默认优先级 100）

pub fn with_condition(self, cond: MaskingCondition) -> Self

设置脱敏条件（链式）

pub fn with_priority(self, priority: u32) -> Self

设置优先级（链式）

pub fn field(&self) -> &str

字段名

pub fn rule(&self) -> &MaskingRule

脱敏规则

pub fn condition(&self) -> Option<&MaskingCondition>

脱敏条件

pub fn priority(&self) -> u32

优先级

pub fn should_apply(&self, data: &HashMap<String, String>) -> bool
