What is the ownership of string literals

String literals in Rust are owned by the program itself and live for the entire duration of execution. They are stored in the binary's read-only data section and have a lifetime of 'static, meaning they never need to be dropped or managed by the runtime.

fn main() {
    let s: &'static str = "hello world";
    // The string "hello world" is owned by the program, not the variable `s`.
    // `s` is just a reference to that static memory.
}

String literals are like text printed directly onto the book's pages; they exist for the entire life of the book and cannot be changed. Unlike variables that hold data you create and delete, these strings are permanent parts of the program. You can only read them, not modify them, because they are baked into the software itself.
