| 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! |
| } |
| ``` |
