Error code E0244

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

This error indicates that too many type parameters were found in a type or trait.

For example, the Foo struct below has no type parameters, but is supplied with two in the definition of Bar:

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

struct Bar<S, T> { x: Foo<S, T> }
}
