rustAnonymous field in Rust struct

Anonymous fields in Rust structs are fields that do not have a name associated with them. They are declared using the struct keyword followed by the type of the field. For example:

struct Point {
    x: i32,
    y: i32,
    // Anonymous field

The anonymous field in the above example is of type i32. It can be accessed using the . operator, just like any other field in the struct. For example:

let p = Point { x: 10, y: 20, 30 };
println!("{}", p.2); // Prints 30

Code explanation

  1. struct Point { - This is the start of the struct declaration.
  2. x: i32, - This is a named field of type i32.
  3. y: i32, - This is another named field of type i32.
  4. i32, - This is the anonymous field of type i32.
  5. let p = Point { x: 10, y: 20, 30 }; - This is how an instance of the struct is created, with the anonymous field being set to 30.
  6. println!("{}", p.2); - This is how the anonymous field is accessed, using the . operator and the index of the field (in this case 2).
