Module vec 

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

Storage Layout

Vec uses Solidity-compatible dynamic array storage:

• Base slot: Stores the array length (number of elements)
• Data slots: Start at keccak256(len_slot), elements packed efficiently

Multi-Slot Support

• Supports both single-slot primitives and multi-slot types (structs, arrays)
• Element at index i starts at slot data_start + i * T::SLOTS

Structs

VecHandler

Type-safe handler for accessing Vec<T> in storage.
