Something went wrong trying to encode or decode a storage address.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooManyKeys

Storage lookup does not have the expected number of keys.

Fields

expected: usize

The number of keys provided in the storage address.

WrongNumberOfHashers

This storage entry in the metadata does not have the correct number of hashers to fields.

Fields

hashers: usize

The number of hashers in the metadata for this storage entry.

fields: usize

The number of fields in the metadata for this storage entry.

NotEnoughBytes

We weren’t given enough bytes to decode the storage address/key.

TooManyBytes

We have leftover bytes after decoding the storage address.

UnexpectedAddressBytes

The bytes of a storage address are not the expected address for decoding the storage keys of the address.

HasherCannotReconstructKey

An invalid hasher was used to reconstruct a value from a chunk of bytes that is part of a storage address. Hashers where the hash does not contain the original value are invalid for this purpose.

Fields

ty_id: u32

Type id of the key’s type.

hasher: StorageHasher

The invalid hasher that caused this error.

Trait Implementations

impl Clone for StorageAddressError

fn clone(&self) -> StorageAddressError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageAddressError

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

Formats the value using the given formatter.

impl Display for StorageAddressError

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

Formats the value using the given formatter.

impl Error for StorageAddressError

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<StorageAddressError> for Error

fn from(source: StorageAddressError) -> Self

Converts to this type from the input type.
