Tuple

Last updated:
Reference:doc.rust-lang.org

Syntax ​

A tuple can contain different types. One value literal tuple needs a trailing comma.

Access its values with tuple.0, tuple.1 etc.

rust
let one_value    = (10,);
let simple_tuple = (10, "Hello", true);
let hello        = simple_tuple.1;

Usage ​

Destructure into simpler types:

rust
let (a, b, c) = simple_tuple;
println!("First: {}, Second: {}, Third: {}", a, b, c);

Printing ​

rust
let one_value    = (10,);
let simple_tuple = (10, "Hello", true);

println!("Debug: {:?}", one_value);
println!("Debug: {:?}", simple_tuple);  // Max 12 elements can be printed
println!("First: {}, Second: {}, Third: {}", simple_tuple.0, simple_tuple.1, simple_tuple.2);
