{ /* private fields */ }

Implementations

impl<A> StorageRawWrapper<A>

where A: StorageReadApi + StorageWriteApi + ManagedTypeApi + ErrorApi,

pub fn new() -> Self

pub fn read<K, V>(&self, storage_key: K) -> V

where K: Into<StorageKey<A>>, V: TopDecode,

Reads storage from the given key, and deserializes the value to the provided type.

Use only if really necessary, storage mappers should be preferred.

pub fn read_from_address<K, V>( &self, address: &ManagedAddress<A>, storage_key: K, ) -> V

where K: Into<StorageKey<A>>, V: TopDecode,

Reads storage from another address (usually a smart contract), from the given key, and deserializes the value to the provided type.

This is a synchronous call, so it only works when both the current contract and the destination are in the same shard.

pub fn write<K, V>(&self, storage_key: K, value: &V)

where K: Into<StorageKey<A>>, V: TopEncode,

Write a serializable value to storage under the given key

Use only if really necessary, storage mappers should be preferred.

fn default() -> StorageRawWrapper<A>
