Enum TokenScope 

pub enum TokenScope {
    Read,
    Write,
    Admin,
}

令牌作用域：read < write < admin，支持偏序比较用于工具调度鉴权。

• read：仅查询已发布文章（知识库）。
• write：read + 文章 CRUD（含草稿）、评论、标签、媒体上传。
• admin：write + 站点设置、代码运行器。

比较语义：scope >= required 表示该令牌有权调用要求 required 作用域的工具。 例如 admin 令牌可调用 read/write/admin 任一工具。

Variants

Read

Write

Admin

Implementations

impl TokenScope

pub fn as_str(self) -> &'static str

数据库存储的字符串形式。

pub fn from_db(s: &str) -> Option<Self>

从数据库字符串解析；非法值返回 None（调用方按业务错误处理，不走 panic）。

fn rank(self) -> u8

数值用于偏序比较：read=1 < write=2 < admin=3。

pub fn grants(self, required: TokenScope) -> bool

该令牌是否满足某工具要求的作用域（self.rank() >= required.rank()）。
