Function backtrack_err

Source 
pub fn backtrack_err<Input, Output, Error, ParseNext>(
    parser: ParseNext,
) -> impl Parser<Input, Output, Error>
where
    Input: Stream,
    Error: ParserError<Input> + ModalError,
    ParseNext: Parser<Input, Output, Error>,
Expand description

Transforms an ErrMode::Cut (unrecoverable) to ErrMode::Backtrack (recoverable)

This attempts the parse, allowing other parsers to be tried on failure, like with winnow::combinator::alt.
