Error code E0599

This error occurs when a method is used on a type which doesn't implement it:

Erroneous code example:

#![allow(unused)] fn main() { struct Mouth; let x = Mouth; x.chocolate(); // error: no method named `chocolate` found for type `Mouth` // in the current scope }

In this case, you need to implement the chocolate method to fix the error:

#![allow(unused)] fn main() { struct Mouth; impl Mouth { fn chocolate(&self) { // We implement the `chocolate` method here. println!("Hmmm! I love chocolate!"); } } let x = Mouth; x.chocolate(); // ok! }
