    IoError(Error),
    ArithmeticError(ArithmeticError),
    TryLockError(Vec<u8>),
    TokioJoinError(JoinError),

}

Main error type for the crate.

Variants

BcsError(Error)

BCS serialization error.

IoError(Error)

Input output error.

ArithmeticError(ArithmeticError)

Arithmetic error

TryLockError(Vec<u8>)

Failed to lock a reentrant collection entry since it is currently being accessed

TokioJoinError(JoinError)

Tokio errors can happen while joining.

StoreError

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

Fields

backend: &'static str

The name of the backend that produced the error

error: Box<dyn Error + Send + Sync>

The inner error

must_reload_view: bool

Whether this error was caused by a journal resolution failure.

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(String)

The database is corrupt: Some entries are missing

PostLoadValuesError

The values are incoherent.

Implementations

impl ViewError

pub fn must_reload_view(&self) -> bool

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

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)>

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.
