Enum FallbackError 

pub enum FallbackError<E> {
    Inner(E),
    FallbackFailed(E),
}

Error type for the fallback service.

Variants

Inner(E)

The inner service failed and no fallback was applied (predicate didn’t match), or the error was transformed via the exception strategy.

FallbackFailed(E)

The fallback service itself failed.

Implementations

impl<E> FallbackError<E>

pub fn is_inner(&self) -> bool

Returns true if this is an inner service error.

pub fn is_fallback_failed(&self) -> bool

Returns true if the fallback itself failed.

pub fn into_inner(self) -> E

Converts into the inner error.

pub fn inner(&self) -> &E

Returns a reference to the inner error.

pub fn map<F, U>(self, f: F) -> FallbackError<U>

where F: FnOnce(E) -> U,

Maps the inner error using the provided function.

Trait Implementations

impl<E: Clone> Clone for FallbackError<E>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for FallbackError<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for FallbackError<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for FallbackError<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

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.
