error[E0029]: only char and numeric types are allowed in range patterns
--> $DIR/E0029-teach.rs:7:9
|
LL | "hello" ..= "world" => {}
| ^^^^^^^^^^^^^^^^^^^ ranges require char or numeric types
|
= note: start type: &'static str
= note: end type: &'static str
= note: In a match expression, only numbers and characters can be matched against a range. This is because the compiler checks that the range is non-empty at compile-time, and is unable to evaluate arbitrary comparison functions. If you want to capture values of an orderable type between two end-points, you can use a guard.
