rust declare variable

Comment

let my_var : type = value; // by default no variables can be changed

// you must define a variable as mutable if you want to change its value
let mut var_name : type = value;

let other_var = var_name; // you can ommit the type if it's easy to guess

// const are variable that can never change, their values must
// be known at compile time and their type must be explicit
const THREE_HOURS_IN_SECONDS: u32 = 60 * 60 * 3;
