Crate fuel_core_storage

source ·
Expand description

The crate fuel-core-storage contains storage types, primitives, tables used by fuel-core. This crate doesn’t contain the actual implementation of the storage. It works around the Database and is used by services to provide a default implementation. Primitives defined here are used by services but are flexible enough to customize the logic when the Database is known.

Modules

  • iter
    Iterators returned by the storage.
  • tables
    The module contains definition of storage tables used by default implementation of fuel services.
  • transactional
    The primitives to work with storage in transactional mode.

Macros

  • not_found
    Creates StorageError::NotFound error with file and line information inside.

Structs

  • ContractsAssetKey
    The FuelVM storage double key.
  • ContractsStateKey
    The FuelVM storage double key.
  • StorageMut
    The wrapper around the storage that supports methods from StorageInspect and StorageMutate.
  • StorageRef
    The wrapper around the storage that supports only methods from StorageInspect.

Enums

  • Error
    Error occurring during interaction with storage

Traits

  • ContractsAssetsStorage
    Storage operations for contract assets.
  • InterpreterStorage
    When this trait is implemented, the underlying interpreter is guaranteed to have full functionality
  • IsNotFound
    The helper trait to work with storage errors.
  • Mappable
    Mappable type with Key and Value.
  • MerkleRootStorage
    Returns the merkle root for the StorageType per merkle Key. The type should implement the StorageMutate for the StorageType. Per one storage, it is possible to have several merkle trees under different Key.
  • StorageAsMut
    Helper trait for StorageMutate to provide user-friendly API to retrieve storage as mutable reference.
  • StorageAsRef
    Helper trait for StorageInspect to provide user-friendly API to retrieve storage as reference.
  • StorageInspect
    Base read storage trait for Fuel infrastructure.
  • StorageMutate
    Base storage trait for Fuel infrastructure.
  • StorageRead
    Base storage trait for Fuel infrastructure.
  • StorageSize
    Base storage trait for Fuel infrastructure.
  • StorageWrite
    Base storage trait for Fuel infrastructure.
