Module types 

Storable type system for EVM storage.

Defines the core traits (StorableType, Storable, FromWord, Packable) and types (Slot, Mapping, Set, vec::VecHandler, array::ArrayHandler) that enable type-safe access to EVM storage slots with automatic packing.

Re-exports

pub use set::Set;

pub use set::SetHandler;

pub use slot::*;

pub use mapping::*;

Modules

array

Fixed-size array handler for the storage traits.

bytes_like

Bytes-like (Bytes, String) implementation for the storage traits.

mapping

Type-safe wrapper for EVM storage mappings (hash-based key-value storage).

primitives 🔒

StorableType, FromWord, and StorageKey implementations for single-word primitives.

sealed 🔒

Private module to seal the Packable trait.

set

OpenZeppelin’s EnumerableSet implementation for EVM storage using Rust primitives. https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/utils/structs/EnumerableSet.sol

slot 🔒

vec

Dynamic array (Vec<T>) implementation for the storage traits.

Structs

HandlerCache 🔒

Cache for computed handlers with stable references.

LayoutCtx

Describes the context in which a storable value is being loaded or stored.

Enums

Layout

Describes how a type is laid out in EVM storage.

Traits

FromWord

Trait for primitive types that fit into a single EVM storage slot.

Handler

Abstracts reading, writing, and deleting values for Storable types.

Packable

Trait for types that can be packed into EVM storage slots.

Storable

High-level storage operations for storable types.

StorableType

Helper trait to access storage layout information without requiring const generic parameter.

StorageKey

Trait for types that can be used as storage mapping keys.
