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)

[−] Expand description

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

BinaryOp(ClassSetBinaryOp)

[−] Expand description

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

Methods

fn clone(&self) -> ClassSet[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl Drop for ClassSet[+]
