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§

  • blueprint
    The module defines structures for the Mappable tables. Each table may have its blueprint that defines how it works with the storage. The table may have a plain blueprint that simply works in CRUD mode, or it may be an SMT-based blueprint that maintains a valid Merkle tree over the storage entries.
  • codec
    The module contains the traits for encoding and decoding the types(a.k.a Codec). It implements common codecs and encoders, but it is always possible to define own codecs.
  • column
    The module defines the Column and default tables used by the current fuel-core codebase. In the future, the Column enum should contain only the required tables for the execution. All other tables should live in the downstream creates in the place where they are really used.
  • iter
    The module defines primitives that allow iterating of the storage.
  • kv_store
    The module provides plain abstract definition of the key-value store.
  • structured_storage
    The module contains the StructuredStorage wrapper around the key-value storage that implements the storage traits for the tables with blueprint.
  • 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.
  • vm_storage
    The wrapper around the storage for VM implements non-storage getters.

Macros§

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

Structs§

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. Per one storage, it is possible to have several merkle trees under different Key.
  • PredicateStorageRequirements
    Storage requirements for predicates.
  • 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.
  • StorageBatchMutate
    The traits allow work with the storage in batches. Some implementations can perform batch operations faster than one by one.
  • 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.
