   1 Expected type did not match the received type.

   3 Erroneous code example:

   5 ```compile_fail,E0308
   6 let x: i32 = "I am not a number!";
   7 //     ~~~   ~~~~~~~~~~~~~~~~~~~~
   8 //      |             |
   9 //      |    initializing expression;
  10 //      |    compiler infers type `&str`
  11 //      |
  12 //    type `i32` assigned to variable `x`
  13 ```

  15 This error occurs when the compiler is unable to infer the concrete type of a
  16 variable. It can occur in several cases, the most common being a mismatch
  17 between two types: the type the author explicitly assigned, and the type the
  18 compiler inferred.
