Enum Protocol 

#[non_exhaustive]
pub enum Protocol {
    Anthropic,
    OpenAiCompatible,
}

对话接口协议：决定走 /v1/messages 还是 /v1/chat/completions。

🔴 线格式是 "anthropic" / "openai_compatible"，与 Protocol::as_str 同一套拼写。 此前靠 rename_all = "snake_case" 自动推出 "open_ai_compatible"， 下游存的是 openai_compatible，前端不得不写一层转换 —— 两种拼写并存， 迟早有一处直接透传而静默错配。

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.

Anthropic

Anthropic 原生：/v1/messages + x-api-key

OpenAiCompatible

OpenAI 兼容：/v1/chat/completions + Authorization: Bearer

Implementations

impl Protocol

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

规范字符串，与 serde 线格式一致。调用方持久化协议时用它。

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

从字符串解析；认不出返回 None。

只收规范拼写 —— 这是给「读自己存的值」用的，存进去的一定是 Self::as_str。 解析别人家分享来的配置（"openai" / "custom" 之类）请用 crate::protocol::parse_profile，那边有宽松的别名映射。

pub const fn default_base_url(self) -> &'static str

用户没填 base_url 时的官方端点。

🔴 带版本段：crate::endpoint 原样拼接、不做推断，少一段就是 404。
