   1 A definition of a method not in the implemented trait was given in a trait
   2 implementation.
   3
   4 Erroneous code example:
   5
   6 ```compile_fail,E0407
   7 trait Foo {
   8     fn a();
   9 }
  10
  11 struct Bar;
  12
  13 impl Foo for Bar {
  14     fn a() {}
  15     fn b() {} // error: method `b` is not a member of trait `Foo`
  16 }
  17 ```
  18
  19 Please verify you didn't misspell the method name and you used the correct
  20 trait. First example:
  21
  22 ```
  23 trait Foo {
  24     fn a();
  25     fn b();
  26 }
  27
  28 struct Bar;
  29
  30 impl Foo for Bar {
  31     fn a() {}
  32     fn b() {} // ok!
  33 }
  34 ```
  35
  36 Second example:
  37
  38 ```
  39 trait Foo {
  40     fn a();
  41 }
  42
  43 struct Bar;
  44
  45 impl Foo for Bar {
  46     fn a() {}
  47 }
  48
  49 impl Bar {
  50     fn b() {}
  51 }
  52 ```
