Module storage

Expand description

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.

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.

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.

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.
