Struct OperationCanceled

pub struct OperationCanceled;

Unit struct used to indicate that an operation was canceled.

Usually used as Result<T, OperationCanceled>.

Trait Implementations

impl Clone for OperationCanceled

fn clone(&self) -> OperationCanceled

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OperationCanceled

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

Formats the value using the given formatter.

impl Display for OperationCanceled

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

Formats the value using the given formatter.

impl Error for OperationCanceled

fn description(&self) -> &'static str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

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

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 From<OperationCanceled> for Error

fn from(oc: OperationCanceled) -> Self

Converts to this type from the input type.

impl PartialEq for OperationCanceled

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
