Enum PluginError 

pub enum PluginError {
    UnsupportedVerb(Verb),
    InvalidArgs(String),
    Other(String),
}

插件能报出来的错误。

刻意只有三种 —— 因为宿主只需要区分三种：不支持这个动词（它可以退化成裸透传）、 入参不对、以及其它一切。

信息量更大的人类可读描述放在 payload 里，宿主原样打到 stderr 上。

Variants

UnsupportedVerb(Verb)

这个后端不支持该动词。

宿主对它有特殊处理：pmpx exec 收到它会退化成裸透传。

InvalidArgs(String)

入参不合法。

Other(String)

其它任何问题。也包括插件 panic —— 宿主只需要知道“它炸了“。

Implementations

impl Eq for PluginError

impl Error for PluginError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
