fuel_core_database/
lib.rs

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