A set for enum variants
It is implemented as a wrapper over the bit-set
crate,
which provides a set for integers values. We use the EnumLike
trait
from the enum_like
crate which allows for a conversion between enum
variant and integer value.
Since an EnumSet
is a wrapper over a BitSet
, and a BitSet
is
a wrapper over a BitVec
, looking at the assembly generated by this crate
should be interesting.
