Enum Error 

pub enum Error {
    InvalidArg(String),
    NotFound(String),
    Kernel(String),
    Panic(String),
    WouldBlock,
    Timeout,
    Cancelled,
    Closed,
    Abi(String),
    Unsupported(String),
    State(String),
}

Variants

InvalidArg(String)

配置 / 参数非法(端口名未定义、拓扑不合法等)。

NotFound(String)

名字查不到(算子未注册、端口不存在)。

Kernel(String)

算子回调返回失败或抛异常。

Panic(String)

跨 FFI 的 panic 兜底。

WouldBlock

非阻塞接口:队列满 / 暂无数据。

Timeout

Cancelled

Closed

端口已关闭 / 图已终止。

Abi(String)

ABI 版本不匹配。

Unsupported(String)

配置用到了本版本尚未实现的特性 —— 宁可报错也不静默忽略。

State(String)

图状态不允许该操作。

Implementations

impl Error

pub fn code(&self) -> i32

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
