Struct MaskingPolicy 

pub struct MaskingPolicy { /* private fields */ }

脱敏策略：为多个字段定义脱敏规则，批量应用

Implementations

impl MaskingPolicy

pub fn new() -> Self

创建空策略

pub fn add_rule(&mut self, field: &str, rule: MaskingRule) -> &mut Self

添加字段脱敏规则（链式）

pub fn get_rule(&self, field: &str) -> Option<&MaskingRule>

获取某字段的脱敏规则

pub fn remove_rule(&mut self, field: &str) -> Option<MaskingRule>

移除某字段的脱敏规则

pub fn field_count(&self) -> usize

已注册字段数

pub fn rules(&self) -> &HashMap<String, MaskingRule>

获取所有规则引用

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

对 HashMap 数据应用脱敏

pub fn apply_to_json(&self, json: &str) -> String

对 JSON 字符串应用脱敏
