## Gas-Efficient Structs

Gas-Efficient Structs are data structures designed to minimize the gas cost of reading and writing data in smart contracts. By grouping related variables into a struct and ordering them to facilitate packing, developers can reduce the number of storage slots used.

In financial derivatives, structs are commonly used to represent positions, orders, or user profiles. Designing these structs for efficiency is a key task for developers, as it directly impacts the performance of the protocol.

This involves understanding how the compiler maps structs to storage and using techniques like packing and alignment to maximize space. A well-designed struct can lead to significant gas savings and a more maintainable codebase.

It is a fundamental practice in professional smart contract engineering, ensuring that complex data is handled in the most efficient way possible.
