Module storage

This module contains functions for decoding storage keys and values.

• See decode_storage_key and decode_storage_value to decode storage keys or values from modern or historic runtimes.
• See decode_storage_key_current and decode_storage_value_current to decode modern storage keys and values.
• See decode_storage_key_legacy and decode_storage_value_legacy to decode historic storage keys and values (with examples).

Structs

• StorageInfo
  Information about a storage entry.
• StorageKey
  Details about a storage key.
• StorageKeyInfo
  Information about a single key within a storage entry.
• StorageKeyPart
  The decoded representation of a storage key.
• StorageKeyPartValue
  Information about the value contained within a storage key part hash.

Enums

• StorageHasher
  Hasher used by storage maps
• StorageInfoError
  An error returned trying to access storage type information.
• StorageKeyDecodeError
  An error returned trying to decode storage bytes.
• StorageValueDecodeError
  An error returned trying to decode storage bytes.

Traits

• StorageTypeInfo
  This is implemented for all metadatas exposed from frame_metadata and is responsible for extracting the type IDs and related info needed to decode storage entries.

Functions

• decode_storage_key
  Decode a storage key, returning information about it.
• decode_storage_key_current
  Decode a storage key in a modern runtime, returning information about it.
• decode_storage_key_legacy
  Decode a storage key in a historic (pre-V14-metadata) runtime, returning information about it.
• decode_storage_value
  Decode a storage value.
• decode_storage_value_current
  Decode a storage value in a modern (V14-metadata-or-later) runtime.
• decode_storage_value_legacy
  Decode a storage value in a historic (pre-V14-metadata) runtime. This is basically just an alias for decode_storage_value.
