Function cucumber_expressions::parse::alternative

pub fn alternative<'a, Input: 'a>(
    input: Input
) -> IResult<Input, Alternative<Input>, Error<Input>> where
    Input: Clone + Display + Offset + InputLength + InputTake + InputTakeAtPosition<Item = char> + Slice<RangeFrom<usize>> + InputIter + for<'s> Compare<&'s str>,
    <Input as InputIter>::Item: AsChar + Copy,
    Error<Input>: ParseError<Input>,
    for<'s> &'s str: FindToken<<Input as InputIter>::Item>, 

Parses an alternative as defined in the grammar spec.

text-in-alternative   = (- alternative-to-escape)
                         | ('\', alternative-to-escape)
alternative-to-escape = ' ' | '(' | '{' | '/' | '\'
