+```compile_fail,E0308
+fn plus_one(x: i32) -> i32 {
+    x + 1
+}
+
+plus_one(\"Not a number\");

+
+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.
