Struct fuel_core_storage::tables::ContractsAssets

pub struct ContractsAssets;

The storage table for contract’s assets balances.

Lifetime is for optimization to avoid clone.

Trait Implementations

impl Mappable for ContractsAssets

type Key = <ContractsAssets as Mappable>::OwnedKey

The key type is used during interaction with the storage. In most cases, it is the same as Self::OwnedKey.

type OwnedKey = ContractsAssetKey

The owned type of the Key retrieving from the storage.

type Value = u64

The value type is used while setting the value to the storage. In most cases, it is the same as Self::OwnedValue, but it is without restriction and can be used for performance optimizations.

type OwnedValue = <ContractsAssets as Mappable>::Value

The owned type of the Value retrieving from the storage.

impl MerkleRootStorage<ContractId, ContractsAssets> for MemoryStorage

fn root(&self, parent: &ContractId) -> Result<[u8; 32], Infallible>

Return the merkle root of the stored Type in the storage.

impl StorageInspect<ContractsAssets> for MemoryStorage

type Error = Infallible

fn get( &self, key: &<ContractsAssets as Mappable>::Key ) -> Result<Option<Cow<'_, u64>>, Infallible>

Retrieve Cow<Value> such as Key->Value.

fn contains_key( &self, key: &<ContractsAssets as Mappable>::Key ) -> Result<bool, Infallible>

Return true if there is a Key mapping to a value in the storage.

impl StorageMutate<ContractsAssets> for MemoryStorage

fn insert( &mut self, key: &<ContractsAssets as Mappable>::Key, value: &u64 ) -> Result<Option<u64>, Infallible>

Append Key->Value mapping to the storage.

fn remove( &mut self, key: &<ContractsAssets as Mappable>::Key ) -> Result<Option<u64>, Infallible>

Remove Key->Value mapping from the storage.
