Main error type for the crate.

Variants

BcsError(Error)

BCS serialization error.

CannotAcquireCollectionEntry

We failed to acquire an entry in a CollectionView or a ReentrantCollectionView.

IoError(Error)

Input output error.

ArithmeticError(ArithmeticError)

Arithmetic error

TryLockError(Vec<u8>)

An error happened while trying to lock.

TokioJoinError(JoinError)

Tokio errors can happen while joining.

StoreError

Errors within the context can occur and are presented as ViewError.

Fields

backend: String

backend can be e.g. RocksDB / DynamoDB / Memory / etc.

error: String

error is the specific problem that occurred within that context

KeyTooLong

The key must not be too long

NotFound(String)

The entry does not exist in memory

InconsistentEntries

The database is corrupt: Entries don’t have the expected hash.

MissingEntries

The database is corrupt: Some entries are missing

PostLoadValuesError

The values are incoherent.

TooLargeValue

The value is too large for the client

BlobsNotFound(Vec<BlobId>)

Some blobs were not found.

EventsNotFound(Vec<EventId>)

Some events were not found.

Implementations

impl ViewError

pub fn not_found<T: Debug>(msg: &str, key: T) -> ViewError

Creates a NotFound error with the given message and key.

Trait Implementations

impl Debug for ViewError

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

Formats the value using the given formatter.

impl Display for ViewError

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

Formats the value using the given formatter.

impl Error for ViewError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
