An associated type was implemented when another trait item was expected.
Erroneous code example:
```compile_fail,E0325
struct Bar;
trait Foo {
const N : u32;
}
impl Foo for Bar {
type N = u32;
// error: item `N` is an associated type, which doesn't match its
// trait `<Bar as Foo>`
}
```
Please verify that the associated type name wasn't misspelled and your
implementation corresponds to the trait definition. Example:
```
struct Bar;
trait Foo {
type N;
}
impl Foo for Bar {
type N = u32; // ok!
}
```
Or:
```
struct Bar;
trait Foo {
const N : u32;
}
impl Foo for Bar {
const N : u32 = 0; // ok!
}
```
