Struct Alternation

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

An alternation of regular expressions.

Fields

span: Span

The span of this alternation.

asts: Vec<Ast>

The alternate regular expressions.

Implementations

impl Alternation

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.

Trait Implementations

impl Clone for Alternation

fn clone(&self) -> Alternation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Alternation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Alternation

fn eq(&self, other: &Alternation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
