Enum near_store::StorageError

pub enum StorageError {
    StorageInternalError,
    TrieNodeMissing,
    StorageInconsistentState(String),
}

Internal

Variants

StorageInternalError

Key-value db internal failure

TrieNodeMissing

Storage is PartialStorage and requested a missing 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.

Trait Implementations

impl BorshDeserialize for StorageError where
    String: BorshDeserialize, 

pub fn deserialize(buf: &mut &[u8]) -> Result<StorageError, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

pub fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

pub fn is_u8() -> bool

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl BorshSerialize for StorageError where
    String: BorshSerialize, 

pub fn serialize<W>(&self, writer: &mut W) -> Result<(), Error> where
    W: Write, 

pub fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>

Serialize this instance into a vector of bytes.

pub fn is_u8() -> bool

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl Clone for StorageError

pub fn clone(&self) -> StorageError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Eq for StorageError

impl Error for StorageError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<StorageError> for StorageError

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

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &StorageError) -> bool

This method tests for !=.
