Tuples

What is a tuple❓

A tuple is a collection of values that can be of different types.

ℹ️ Tuples are usually used to return multiple values from a function.

ℹ️ Tuples can contain other tuples.

Declaring a tuple

A tuple can be declared with the following syntax:

let zoo = ("🦍 Gorilla", "🦊 Fox", "🦓 Zebra", "🐘 Elephant");

Accessing a tuple

We can access different values in a tuple with the following syntax: tuple.index

Example, print the first value in the tuple:

let zoo = ("🦍 Gorilla", "🦊 Fox", "🦓 Zebra", "🐘 Elephant");

println!("The first animal in the zoo is the ", zoo.0);

Output:

The first animal in the zoo is the 🦍 Gorilla

Extracting values from a tuple🚪

We can extract values from a tuple and store them in variables with the following syntax:

let zoo = ("🦍 Gorilla", "🦊 Fox", "🦓 Zebra", "🐘 Elephant");

let (a, b, c, d) = zoo;

println!("In the zoo, there is a {}, a {}, a {}, and an {}", a, b, c, d);

Output:

In the zoo, there is a 🦍 Gorilla, a 🦊 Fox, a 🦓 Zebra, and an 🐘 Elephant
