#### Note: this error code is no longer emitted by the compiler. You gave too many lifetime arguments. 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. Example: ``` struct Foo { value: String } impl Foo { // it can be written like this fn get_value<'a>(&'a self) -> &'a str { &self.value } // but the compiler works fine with this too: fn without_lifetime(&self) -> &str { &self.value } } fn main() { let f = Foo { value: "hello".to_owned() }; println!("{}", f.get_value()); println!("{}", f.without_lifetime()); } ```
