How to pass a string literal

To pass a string literal in Rust, you can simply use double quotation marks to enclose the string. Here's an example:

fn main() {
    let my_string = "Hello, world!";
    println!("{}", my_string);

In this example, the string literal "Hello, world!" is assigned to the variable my_string. The println! macro is then used to print the value of my_string to the console.

That's it! You can pass string literals in Rust by enclosing them in double quotation marks.
