Module fabric_support::storage[−][src]

Stuff to do with the runtime’s storage.

Modules

child	Operation on runtime child storages.
hashed	Operation on runtime storage using hashed keys.
migration	Some utilities for helping access storage with arbitrary key types.
types	Storage types to build abstraction on storage, they implements storage traits such as StorageMap and others.
unhashed	Operation on unhashed runtime storage.

Iterate over a prefix and decode raw_key and raw_value into T.

Describes on what should happen with a storage transaction.

IterableStorageDoubleMap	A strongly-typed double map in storage whose secondary keys and values can be iterated over.
IterableStorageMap	A strongly-typed map in storage whose keys and values can be iterated over.
StorageAppend	Marker trait that will be implemented for types that support the `storage::append` api.
StorageDecodeLength	Marker trait that will be implemented for types that support to decode their length in an effificent way. It is expected that the length is at the beginning of the encoded object and that the length is a `Compact<u32>`.
StorageDoubleMap	An implementation of a map with a two keys.
StorageMap	A strongly-typed map in storage.
StoragePrefixedMap	Trait for maps that store all its value after a unique prefix.
StorageValue	A trait for working with macro-generated storage values under the tetcore storage API.

require_transaction	Assert this method is called within a storage transaction. This will panic if is not called within a storage transaction.
with_transaction	Execute the supplied function in a new storage transaction.
