Trait Implementations

impl<E1: Debug, E2: Debug> Debug for DualStoreError<E1, E2>

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

Formats the value using the given formatter.

impl<E1, E2> Display for DualStoreError<E1, E2>

where E1: Display, E2: Display,

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

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<E1, E2> From<Error> for DualStoreError<E1, E2>

fn from(source: Error) -> Self

Converts to this type from the input type.

const BACKEND: &'static str = "dual_store"

The name of the backend.

fn must_reload_view(&self) -> bool

Returns true if this error represents a journal resolution failure, which may leave storage in an inconsistent state requiring a view reload.
