Enum StorageError 

pub enum StorageError {
    InvalidAccountsPath,
    StorageInUse,
    NoStorage,
    NoCurrentTransaction,
    PathError(PathError),
    RuntimeError(RuntimeError),
}

Account transaction errors

All errors that may occur when using the accoun transaction API. When the error variant encapsulates some other error type, this is where the error originates from the durable storage interface on the host runtime.

Variants

InvalidAccountsPath

Invalid accounts path. Could not get the string representation of the accounts storage path.

StorageInUse

Some path in durable storage was already in use when the storage interface needed to use it for holding a transaction.

NoStorage

Some storage operation was tried, but the storage doesn’t even have the base (original) layer of accounts available.

NoCurrentTransaction

Some transaction operation, commit or rollback, was attempted while no transaction was in progress.

PathError(PathError)

Tried to create an invalid path to accounts. Check that the path to the storage for original account values (the base layer) starts with a ‘/’ character (it should).

RuntimeError(RuntimeError)

Some error was encountered while using the durable storage. This may happen when doing some transaction operation.

Trait Implementations

impl Clone for StorageError

fn clone(&self) -> StorageError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StorageError

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Eq for StorageError

impl Error for StorageError

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<PathError> for StorageError

fn from(path_error: PathError) -> Self

Converts to this type from the input type.

impl From<RuntimeError> for StorageError

fn from(runtime_error: RuntimeError) -> Self

Converts to this type from the input type.

impl PartialEq for StorageError

fn eq(&self, other: &StorageError) -> 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.
