Erroneous code example: + +```compile_fail,E0107 +fn f() {} + +fn main() { + f::<'static>() // error: wrong number of lifetime arguments: + // expected 0, found 1 +} +``` + +Please check you give the right number of lifetime arguments. Example: + +``` +fn f() {} + +fn main() { + f() // ok! +} +``` + +It's also important to note that the Rust compiler can generally +determine the lifetime by itself.
