Struct regex_syntax::ast::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<'arbitrary> Arbitrary<'arbitrary> for Alternation

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

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<Alternation> for Alternation

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

This method tests for self and other values to be equal, and is used by ==.

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

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