Trait Implementations

impl<Input: Clone> Clone for Alternative<Input>

fn clone(&self) -> Alternative<Input>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Input: Debug> Debug for Alternative<Input>

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

Formats the value using the given formatter.

impl<Input> IntoRegexCharIter<Input> for Alternative<Input>where Input: Display + InputIter, <Input as InputIter>::Item: AsChar,

Available on crate feature into-regex only.

type Iter = Either<<Optional<Input> as IntoRegexCharIter<Input>>::Iter, Map<EscapeForRegex<Map<<Input as InputIter>::IterElem, fn(_: <Input as InputIter>::Item) -> char>>, fn(_: char) -> Result<char, ParameterError<Input>>>>

Type of an Iterator performing the expansion.

fn into_regex_char_iter(self) -> Self::Iter

Consumes this AST element returning an Iterator over chars transformable into a Regex.

impl<Input: PartialEq> PartialEq<Alternative<Input>> for Alternative<Input>

fn eq(&self, other: &Alternative<Input>) -> 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.
