Callback functions the Parser can use to notify the user of errors encountered while parsing.

Provided methods

fn unexpected_token(
    &mut self,
    _found: TokenKind,
    _span: Span,
    _expected: &[TokenKind]
)

We were looking for one or more tokens, but got a different

fn unexpected_eof(&mut self, _expected: &[TokenKind])

The end-of-input was encountered when more input was expected.

fn mangled_input(&mut self, _input: &str, _span: Span)
