Enum Error

pub enum Error<S, E> {
    Aborted(S),
    LostWaiter,
    App(E),
}

Errors that can be returned by the swctx library.

Variants

Aborted(S)

The SetCtx was dropped while in state ‘S’.

LostWaiter

The WaitCtx was dropped.

This will be returned by SetCtx if it attempts to update the context if there’s no longer a WaitCtx to receive the changes.

App(E)

The SetCtx triggered an application-defined error.

Implementations

impl<S, E> Error<S, E>

pub fn into_apperr(self) -> Option<E>

Return application-specific error, if set.

If the error is not Error::App(E) then return None, otherwise return Some(E).

pub fn unwrap_apperr(self) -> E

Return application-specific error.

Panics

This method will panic if the error is not Error::App(E).

Trait Implementations

impl<S: Debug, E: Debug> Debug for Error<S, E>

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

Formats the value using the given formatter.

impl<S, E> Display for Error<S, E>

where E: Error,

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

Formats the value using the given formatter.

impl<S: Debug, E> Error for Error<S, E>

where E: 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<S: PartialEq, E: PartialEq> PartialEq for Error<S, E>

fn eq(&self, other: &Error<S, E>) -> 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.
