{"$message_type":"diagnostic","message":"mismatched types","code":{"code":"E0308","explanation":"Expected type did not match the received type.
Erroneous code examples:
```compile_fail,E0308
fn plus_one(x: i32) -> i32 {
x + 1
}
plus_one(\"Not a number\");
// ^^^^^^^^^^^^^^ expected `i32`, found `&str`
if \"Not a bool\" {
// ^^^^^^^^^^^^ expected `bool`, found `&str`
}
let x: f32 = \"Not a float\";
// --- ^^^^^^^^^^^^^ expected `f32`, found `&str`
// |
// expected due to this
```
This error occurs when an expression was used in a place where the compiler
expected an expression of a different type. It can occur in several cases, the
most common being when calling a function and passing an argument which has a
different type than the matching type in the function declaration.
