Every function declares an expected return type, either explicitly via the return type annotation or implicitly through the function body. When the body of a function produces a value of a different type than what the signature promises, the compiler emits <strong>error E0514</strong>. This error surfaces most frequently when working with traits, generics, and complex return type annotations.</p>
