Struct ColumnMaskingRule 

pub struct ColumnMaskingRule {
    pub table: String,
    pub column: String,
    pub masking_function: MaskingFunction,
    pub applicable_permissions: PermissionPredicate,
}

列级脱敏规则

ORM 层强制执行，不可绕过。未配置脱敏规则的敏感列默认拒绝读取（安全优先）。

Fields

table: String

表名

column: String

列名

masking_function: MaskingFunction

脱敏函数

applicable_permissions: PermissionPredicate

适用权限（未授权租户/角色才脱敏）

pub fn mask(&self, value: &str) -> String
