Enum TokenLifetime 

pub enum TokenLifetime {
    Days1,
    Days7,
    Days30,
    Days90,
    Never,
}

令牌有效期预设：管理员在 UI 上从下拉菜单选择。

序列化形式供前端选择回传（days1 / days7 / days30 / days90 / never）。 Never 对应 expires_at = NULL（长期令牌）；其余按当前时间 + N 天计算。

Variants

Days1

1 天（默认推荐：最小权限、轮换友好）。

Days7

7 天。

Days30

30 天。

Days90

90 天。

Never

永不过期（expires_at = NULL）。仅用于可信长期客户端。

Implementations

impl TokenLifetime

fn expires_at(self) -> Option<DateTime<Utc>>

计算签发时刻对应的过期时间戳（UTC）。Never 返回 None。

Trait Implementations

impl Clone for TokenLifetime

fn clone(&self) -> TokenLifetime

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TokenLifetime

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TokenLifetime

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TokenLifetime

fn eq(&self, other: &TokenLifetime) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TokenLifetime

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
