Small correction: contrary to what the post claims this does not compile: fn main() { let s = String::from("hello"); foo(s); println!("{}", s); } fn foo(le_string: String) -> String { println!("{}", le_string); le_string } This does, which is probably what the author meant: fn main() { let s = String::from("hello"); let s = foo(s); println!("{}", s); } fn foo(le_string: String) -> String { println!("{}", le_string); le_string } Great post!
