Error code E0243

Note: this error code is no longer emitted by the compiler.

This error indicates that not enough type parameters were found in a type or trait.

For example, the Foo struct below is defined to be generic in T, but the type parameter is missing in the definition of Bar:

#![allow(unused)]
fn main() {
struct Foo<T> { x: T }

struct Bar { x: Foo }
}
