Error code E0576
An associated item wasn't found in the given type.
Erroneous code example:
#![allow(unused)] fn main() { trait Hello { type Who; fn hello() -> <Self as Hello>::You; // error! } }
In this example, we tried to use the nonexistent associated type You
of the
Hello
trait. To fix this error, use an existing associated type:
#![allow(unused)] fn main() { trait Hello { type Who; fn hello() -> <Self as Hello>::Who; // ok! } }
