Module slot_identifier 

Storage slot identification and decoding utilities for Solidity storage layouts.

This module provides functionality to identify and decode storage slots based on Solidity storage layout information from the compiler.

Structs

DecodedSlotValues

Decoded storage slot values

SlotIdentifier

Storage slot identifier that uses Solidity [StorageLayout] to identify storage slots.

SlotInfo

Information about a storage slot including its label, type, and decoded values.

StorageTypeInfo

Wrapper type that holds both the original type label and the parsed DynSolType.

Constants

ENCODING_BYTES

“bytes” encoding type for bytes and string types, which use either inplace or keccak256 hash-based storage depending on length

ENCODING_DYN_ARRAY

“dynamic_array” encoding type for dynamic arrays, which uses keccak256 hash-based storage

ENCODING_INPLACE

“inplace” encoding type for variables that fit in one storage slot i.e 32 bytes

ENCODING_MAPPING

“mapping” encoding type for Solidity mappings, which use keccak256 hash-based storage

Functions

get_array_base_indices 🔒

Returns the base indices for array types, e.g. “[0][0]” for 2D arrays.

is_struct

Checks if a given type label represents a struct type.

parse_sol_type 🔒

Parses a storage type label into a [DynSolType], returning None for labels that have no direct ABI equivalent (mappings, structs).

serialize_mapping_keys 🔒

Custom serializer for mapping keys

serialize_slot_type 🔒

Custom serializer for StorageTypeInfo that only outputs the label
