2. Rust's enums look awesome but are only mostly awesome:
a. Pattern matching on them can lead to some pretty deep
indentation which is a bit annoying.
b. There's no good way to have multiple cases handled by the same
code like you can with a C switch; you have to either repeat it or
break it out into a generic helper.
Do you know that you can use "|" for having multiple cases handled by the same
code?
enum MyEnum {
A,
B,
C
}
fn main() {
let val = MyEnum::A;
match val {
MyEnum::A | MyEnum::B => {println!("case A or case B");},
MyEnum::C => {println!("case C");}
}
}
