Explain the concept of generics in Rust and how they enhance code reusability.

Generics in Rust are a powerful language feature that allows you to write code that can be used with different types without sacrificing type safety. They provide a way to write reusable code by parameterizing functions, structs, and enums over types, enabling flexibility and code reusability. The concept of generics revolves around creating generic types or functions that can operate on multiple types. Type parameters, represented by identifiers such as 'T', 'U', or any other chosen name, are used to specify these generic types or functions. When the code is used, these type parameters are replaced with concrete types, allowing the generic code to work with various data types. The key benefits of generics in Rust and how they enhance code reusability are as follows: 1. Code reusability: Generics enable you to write generic functions, structs, and enums that can be used with different types. Rather than writing separate code for each type, you can define a single implementation that works universally. This reduces code duplication, promotes modularity, and improves maintainability. It allows you to write generic algorithms and data structures that can be used across different typ....
