source · 
pub fn backtrack_err<I, O, E: ParseError<I>, F>(
    parser: F

    I: Stream,
    F: Parser<I, O, E>,
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::branch::alt.
