Enum BookSourceError 

pub enum BookSourceError {
    Config(ConfigError),
    Eval(EvalError),
    Fetch(FetchError),
    Missing(&'static str),
}

书源 v2 顶层错误。

Variants

Config(ConfigError)

配置(书源 JSON)解析失败。

Eval(EvalError)

规则求值失败。

Fetch(FetchError)

取页失败。

Missing(&'static str)

操作所需的配置缺失(如未配置 search/explore)。

Implementations

impl BookSourceError

pub fn is_challenge(&self) -> bool

是否为「被反爬挑战拦截」(如 Cloudflare 托管挑战)。 用于诊断/降级:据此给出精确提示而非笼统失败,并决定是否升级浏览器取页。

Trait Implementations
