A group of flags.
This corresponds only to the sequence of flags themselves, e.g., is-u
.
The span of this group of flags.
A sequence of flag items. Each item is either a flag or a negation
operator.
Add the given item to this sequence of flags.
If the item was added successfully, then None
is returned. If the
given item is a duplicate, then Some(i)
is returned, where
items[i].kind == item.kind
.
Returns the state of the given flag in this set.
If the given flag is in the set but is negated, then Some(false)
is
returned.
If the given flag is in the set and is not negated, then Some(true)

Otherwise, None
is returned.
