Enum UserAttribution 

#[non_exhaustive]
#[repr(u8)]
pub enum UserAttribution {
    Cn = 1,
    Us = 2,
    Sg = 3,
    Au = 4,
    Jp = 5,
    Hk = 6,
}

用户归属地（对齐 C++ FTLogin/Src/ftlogin/ftlogin_def.h:261-270 和 config/impl/user_attr_config.cpp:8-15）

salt 响应里 user_attribution 字段决定认证域名：

• CN / HK → auth.futunn.com
• US / SG / AU / JP → auth.moomoo.com

海外账号（moomoo）如果发到 futunn 域名会返回 error_code=11（误导为“验证码“， 实际是服务端校验失败），必须按 attribution 切域名。

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cn = 1

Us = 2

Sg = 3

Implementations

impl UserAttribution

pub fn from_u32(v: u32) -> Option<Self>

从 salt 响应的 user_attribution 整数字段解析。 未知值（0 或 7+）返回 None，让调用方走 fallback（默认 futunn）。

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

对齐 C++ user_attr_config.cpp:8-15 的映射表。

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

人读地区代码（日志 / 凭据文件用）。

pub fn to_conn_identity(self) -> u32

TCP 登录 ReqEncryptData.conn_identity 字段： 对齐 C++ FTConnCmn.proto ConnIdentity enum，UserAttribution 数值直接对应 (CN=1, US=2, SG=3, AU=4, JP=5, HK=6，见 user_attr_config.cpp:8-15)

Trait Implementations

impl Clone for UserAttribution

fn clone(&self) -> UserAttribution

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UserAttribution

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UserAttribution

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for UserAttribution

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UserAttribution

fn eq(&self, other: &UserAttribution) -> 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 UserAttribution

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for UserAttribution
