Function winnow::ascii::take_escaped

pub fn take_escaped<'i, Input, Error, Normal, Escapable, NormalOutput, EscapableOutput>(
    normal: Normal,
    control_char: char,
    escapable: Escapable
) -> impl Parser<Input, <Input as Stream>::Slice, Error>
where
    Input: StreamIsPartial + Stream + Compare<char> + 'i,
    Normal: Parser<Input, NormalOutput, Error>,
    Escapable: Parser<Input, EscapableOutput, Error>,
    Error: ParserError<Input>,

Recognize the input slice with escaped characters.
