Expand description
Something went wrong trying to encode or decode a storage address.
Variants (Non-exhaustive)§
This enum is marked as 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.
WrongNumberOfHashers
This storage entry in the metadata does not have the correct number of hashers to fields.
Fields
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
§
hasher: StorageHasher
The invalid hasher that caused this error.
