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.

impl Eq for Alternation

impl StructuralPartialEq for Alternation

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
