Is it possible to somehow automatically derive
collections::enum_set::CLike for a enum? The idea of writing
impl CLike for MyEnum {
fn to_uint(&self) -> uint {
return *self as uint;
}
fn from_uint(n: uint) -> Flag {
match n {
0 => EnumConst1,
...
_ => fail!("{} does not match any enum case, n)
}
}
}
just to get a type safe bit set EnumSet<MyEnum> is rather discouraging.
On a related note I see that EnumSet never checks that CLike::to_int
result stays below the word size. Is it a bug?
