"##,

E0118: r##"
Rust can't find a base type for an implementation you are providing, or the type
cannot have an implementation. For example, only a named type or a trait can
have an implementation:

```
type NineString = [char, ..9] // This isn't a named type (struct, enum or trait)
impl NineString {
// Some code here
}
```

In the other, simpler case, Rust just can't find the type you are providing an
impelementation for:

```
impl SomeTypeThatDoesntExist { }
```
