A character class set.
This type corresponds to the internal structure of a bracketed character
class. That is, every bracketed character is one of two types: a union of
items (literals, ranges, other bracketed classes) or a tree of binary set
operations.
An item, which can be a single literal, range, nested character class
or a union of items.
A single binary operation (i.e., &&, -- or ~~).
Build a set from a union.
Return the span of this character class set.
A custom Drop
impl is used for ClassSet
such that it uses constant
stack space but heap space proportional to the depth of the ClassSet
.
