Struct AsyncOperationError 

pub struct AsyncOperationError<T> { /* private fields */ }

Error from an async consuming operation.

A callback-lease conflict occurs before native work and retains the reusable typestate. Worker failure or an internal state mismatch returns no state because the facade cannot prove that retrying it would be sound.

Implementations

impl<T> AsyncOperationError<T>

pub const fn error(&self) -> &Error

Returns the operation error.

pub const fn state(&self) -> Option<&T>

Returns reusable state only when native work is known not to have begun.

pub fn into_parts(self) -> (Option<T>, Error)

Separates the optional reusable state and operation error.

Trait Implementations

impl<T> Debug for AsyncOperationError<T>

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

Formats the value using the given formatter.

impl<T> Display for AsyncOperationError<T>

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

Formats the value using the given formatter.

impl<T> Error for AsyncOperationError<T>

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.
