   1 {
   2   "message": "cannot find type `Iter` in this scope",
   3   "code": {
   4     "code": "E0412",
   5     "explanation": "
   6 The type name used is not in scope.
   7
   8 Erroneous code examples:
   9
  10 ```compile_fail,E0412
  11 impl Something {} // error: type name `Something` is not in scope
  12
  13 // or:
  14
  15 trait Foo {
  16     fn bar(N); // error: type name `N` is not in scope
  17 }
  18
  19 // or:
  20
  21 fn foo(x: T) {} // type name `T` is not in scope
  22 ```
  23
  24 To fix this error, please verify you didn't misspell the type name, you did
  25 declare it or imported it into the scope. Examples:
  26
  27 ```
  28 struct Something;
  29
  30 impl Something {} // ok!
  31
  32 // or:
  33
  34 trait Foo {
  35     type N;
  36
  37     fn bar(_: Self::N); // ok!
  38 }
  39
  40 // or:
  41
  42 fn foo<T>(x: T) {} // ok!
  43 ```
  44
  45 Another case that causes this error is when a type is imported into a parent
  46 module. To fix this, you can follow the suggestion and use File directly or
  47 `use super::File;` which will import the types from the parent namespace. An
  48 example that causes this error is below:
  49
  50 ```compile_fail,E0412
  51 use std::fs::File;
  52
  53 mod foo {
  54     fn some_function(f: File) {}
  55 }
  56 ```
  57
  58 ```
  59 use std::fs::File;
  60
  61 mod foo {
  62     // either
  63     use super::File;
  64     // or
  65     // use std::fs::File;
  66     fn foo(f: File) {}
  67 }
  68 # fn main() {} // don't insert it for us; that'll break imports
  69 ```
