Enum AllocationSessionError 

#[non_exhaustive]
pub enum AllocationSessionError<E> {
    UnknownStableKey(StableKey),
    Substrate(E),
}

AllocationSessionError

Failure to open through a validated allocation session.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnknownStableKey(StableKey)

Stable key was not part of the validated allocation snapshot.

Substrate(E)

Storage substrate failed to open the validated slot.

Trait Implementations

impl<E: Clone> Clone for AllocationSessionError<E>

fn clone(&self) -> AllocationSessionError<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for AllocationSessionError<E>

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

Formats the value using the given formatter.

impl<E> Display for AllocationSessionError<E>

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

Formats the value using the given formatter.

impl<E: Eq> Eq for AllocationSessionError<E>

impl<E> Error for AllocationSessionError<E>

where Self: Debug + Display,

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<E: PartialEq> PartialEq for AllocationSessionError<E>

fn eq(&self, other: &AllocationSessionError<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.
