rustHow do I create a class variable in Rust?

Class variables in Rust are called static variables. They are declared using the static keyword and can be accessed from anywhere in the code.

Example code

static MY_VAR: i32 = 5;

fn main() {
    println!("The value of MY_VAR is: {}", MY_VAR);
}

Output example

The value of MY_VAR is: 5

• static: keyword used to declare a static variable
• MY_VAR: name of the static variable
• i32: type of the static variable
• 5: value of the static variable
• println!: macro used to print the value of the static variable
