Struct regex_syntax::ast::ClassSetUnion

[+] Show declaration

pub struct ClassSetUnion {
    pub span: Span,
    pub items: Vec<ClassSetItem>,
}

[−] Expand description

A union of items inside a character class set.

Fields

span: Span

[−] Expand description

The span of the items in this operation. e.g., the a-z0-9 in [^a-z0-9]

items: Vec<ClassSetItem>

[−] Expand description

The sequence of items that make up this union.

Methods

impl ClassSetUnion[−]

pub fn push(&mut self, item: ClassSetItem)[−]

Push a new item in this union.

The ending position of this union's span is updated to the ending position of the span of the item given. If the union is empty, then the starting position of this union is set to the starting position of this item.

In other words, if you only use this method to add items to a union and you set the spans on each item correctly, then you should never need to adjust the span of the union directly.

pub fn into_item(self) -> ClassSetItem[−]

Return this union as a character class set item.

If this union contains zero items, then an empty union is returned. If this concatenation contains exactly 1 item, then the corresponding item is returned. Otherwise, ClassSetItem::Union is returned.
