Enum SingleExpression

pub enum SingleExpression<Input> {
    Alternation(Alternation<Input>),
    Optional(Optional<Input>),
    Parameter(Parameter<Input>),
    Text(Input),
    Whitespaces(Input),
}

single-expression defined in the grammar spec, representing a single entry of an Expression.

See parse::single_expression() for the detailed grammar and examples.

Variants

Alternation(Alternation<Input>)

alternation expression.

Optional(Optional<Input>)

Parameter(Parameter<Input>)

parameter expression.

Text(Input)

text-without-whitespace+ expression.

Whitespaces(Input)

whitespace+ expression.

Trait Implementations

impl<Input: Clone> Clone for SingleExpression<Input>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Input: Debug> Debug for SingleExpression<Input>

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

Formats the value using the given formatter.

impl<I> IntoRegexCharIter<I> for SingleExpression<I>

where I: Clone + Display + Input, <I as Input>::Item: AsChar,

Available on crate feature into-regex only.

type Iter = Either<<Alternation<I> as IntoRegexCharIter<I>>::Iter, Either<<Optional<I> as IntoRegexCharIter<I>>::Iter, Either<<Parameter<I> as IntoRegexCharIter<I>>::Iter, Map<EscapeForRegex<Map<<I as Input>::Iter, fn(<I as Input>::Item) -> char>>, fn(char) -> Result<char, ParameterError<I>>>>>>

Type of 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 for SingleExpression<Input>

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