pub enum ClassSet {
    Item(ClassSetItem),
    BinaryOp(ClassSetBinaryOp),
}
Expand description

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.

Variants§

§

Item(ClassSetItem)

An item, which can be a single literal, range, nested character class or a union of items.

§

BinaryOp(ClassSetBinaryOp)

A single binary operation (i.e., &&, – or ~~).
