## Struct

A struct is a user-defined data type in Solidity that allows developers to group related variables together under a single name. Structs are fundamental for organizing complex data, such as user profiles, order books, or liquidity pool information, within a smart contract.

By using structs, developers can manage state more efficiently and improve code readability. In the context of Diamond Storage, structs are used to encapsulate all state variables associated with a specific facet, providing a clean and safe way to isolate data.

They are an essential tool for structured data management in blockchain programming.
