pub struct Alternation {
    pub span: Span,
    pub asts: Vec<Ast>,
}
Expand description

An alternation of regular expressions.

Fields§

§span: Span

The span of this alternation.

§asts: Vec<Ast>

The alternate regular expressions.

Implementations§

source§

impl Alternation

source

pub fn into_ast(self) -> Ast

Return this alternation as an AST.

If this alternation contains zero ASTs, then Ast::Empty is returned. If this alternation contains exactly 1 AST, then the corresponding AST is returned. Otherwise, Ast::Alternation is returned.
