Enum DatabaseError 

pub enum DatabaseError {
    Read(DatabaseErrorInfo),
    Write(DatabaseErrorInfo),
    Custom(AnyError),
}

Errors surfaced by the underlying state database when arb-storage reads or writes a slot.

The underlying Database::Error is erased here so that callers do not have to propagate a generic <DBErr> parameter through every layer.

Variants

Read(DatabaseErrorInfo)

The database returned an error while reading a slot.

Write(DatabaseErrorInfo)

The database returned an error while writing a slot.

Custom(AnyError)

Catch-all wrapper for implementation-specific errors that do not fit Read or Write.

Implementations

impl DatabaseError

pub fn custom<E>(error: E) -> Self

where E: Error + Send + Sync + 'static,

Wraps any Error as a DatabaseError::Custom.

Trait Implementations

impl Clone for DatabaseError

fn clone(&self) -> DatabaseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatabaseError

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

Formats the value using the given formatter.

impl Display for DatabaseError

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

Formats the value using the given formatter.

impl Error for DatabaseError

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 From<DatabaseError> for StorageError

fn from(source: DatabaseError) -> Self

Converts to this type from the input type.
