   1 An associated const was implemented when another trait item was expected.
   2 Erroneous code example:
   3
   4 ```compile_fail,E0323
   5 trait Foo {
   6     type N;
   7 }
   8
   9 struct Bar;
  10
  11 impl Foo for Bar {
  12     const N : u32 = 0;
  13     // error: item `N` is an associated const, which doesn't match its
  14     //        trait `<Bar as Foo>`
  15 }
  16 ```
  17
  18 Please verify that the associated const wasn't misspelled and the correct trait
  19 was implemented. Example:
  20
  21 ```
  22 struct Bar;
  23
  24 trait Foo {
  25     type N;
  26 }
  27
  28 impl Foo for Bar {
  29     type N = u32; // ok!
  30 }
  31 ```
  32
  33 Or:
  34
  35 ```
  36 struct Bar;
  37
  38 trait Foo {
  39     const N : u32;
  40 }
  41
  42 impl Foo for Bar {
  43     const N : u32 = 0; // ok!
  44 }
  45 ```
