{"message":"mismatched types","code":{"code":"E0308","explanation":"Expected type did not match the received type.
Erroneous code example:
```compile_fail,E0308
let x: i32 = \"I am not a number!\";
// ~~~ ~~~~~~~~~~~~~~~~~~~~
// | |
// | initializing expression;
// | compiler infers type `&str`
// |
// type `i32` assigned to variable `x`
```
This error occurs when the compiler is unable to infer the concrete type of a
variable. It can occur in several cases, the most common being a mismatch
between two types: the type the author explicitly assigned, and the type the
compiler inferred.
