What is the meaning of Tuple and Tuple of Reference in Rust?

edit

A tuple in Rust is an ordered collection of fixed number of elements of different types, where each element can be accessed by its index. For example, a tuple in Rust can be declared as (i32, f32, &str). This tuple consists of three elements: an integer of type i32, a floating point number of type f32, and a reference to a string slice of type &str.

A tuple of reference in Rust is a tuple that contains references to other values. For example, a tuple of reference can be declared as (&i32, &f32, &str). This tuple contains three elements, each of which is a reference to another value.
