Enum ScopeError 

pub enum ScopeError<E = TransportError> {
    ClosureError(E),
    AutoPollError(Vec<TransportError>),
}

Error returned by Channel::scope.

Distinguishes between errors originating from the user’s closure and errors discovered during automatic polling of outstanding work requests.

Variants

ClosureError(E)

The user’s closure returned an error.

AutoPollError(Vec<TransportError>)

The closure succeeded, but one or more auto-polled work requests failed.

Trait Implementations

impl<E: Debug> Debug for ScopeError<E>

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

impl<E> Display for ScopeError<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for ScopeError<E>

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

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

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

impl<E> From<E> for ScopeError<E>

fn from(source: E) -> Self

Converts to this type from the input type.
