let tuple = (1, 'A' , "Cool", 78, true);

let some\_vector = vec![1,2,3,4,5]; 

A vector is declared using the vec! macro.

let mut array: [ i64; 4] = [1,2,3,4];
let mut slices: &[i64] = &array[0..3] // Lower range is inclusive and upper range is exclusive
println!("The elements of the slices are : {slices:?}");

let mut array: [i32 ; 3] = [2,6,10];
array[1] = 4;
array[2] = 6;

Use the mut keyword to make it mutable.
