Define generic structs in Rust by adding a type parameter in angle brackets to create flexible, reusable data structures.
Use generic structs by defining a type parameter in angle brackets after the struct name and using it for field types. This allows the struct to hold any data type that satisfies the constraints you specify.
struct Point<T> {
x: T,
y: T,
}
let integer_point = Point { x: 5, y: 10 };
let float_point = Point { x: 5.0, y: 10.0 };
Generic structs are like reusable templates for data containers. Instead of writing separate code for integers, strings, or floats, you write one struct that works with any type you choose. It is similar to a box that can hold a ball, a book, or a toy without needing a different box for each item.
