Enum StorageError

pub enum StorageError {
    StorageInternalError,
    MissingTrieValue(MissingTrieValueContext, CryptoHash),
    UnexpectedTrieValue,
    StorageInconsistentState(String),
    FlatStorageBlockNotSupported(String),
    MemTrieLoadingError(String),
}

Errors which may occur during working with trie storages, storing trie values (trie nodes and state values) by their hashes.

Variants

StorageInternalError

Key-value db internal failure

MissingTrieValue(MissingTrieValueContext, CryptoHash)

Requested trie value by its hash which is missing in storage.

UnexpectedTrieValue

Found trie node which shouldn’t be part of state. Raised during validation of state sync parts where incorrect node was passed. TODO (#8997): consider including hash of trie node.

StorageInconsistentState(String)

Either invalid state or key-value db is corrupted. For PartialStorage it cannot be corrupted. Error message is unreliable and for debugging purposes only. It’s also probably ok to panic in every place that produces this error. We can check if db is corrupted by verifying everything in the state trie.

FlatStorageBlockNotSupported(String)

Flat storage error, meaning that it doesn’t support some block anymore. We guarantee that such block cannot become final, thus block processing must resume normally.

MemTrieLoadingError(String)

In-memory trie could not be loaded for some reason.

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 Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

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<StorageError> for RuntimeError

fn from(e: StorageError) -> 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.
