type keyword_state
type te
type 'c pattern
type ty_pattern =
| TPattern : 'a pattern -> ty_pattern
type peek_error = unit
type 'a parser_v = ('a, peek_error) Stdlib.result

Recoverable parsing errors are signaled use Error. To be correctly recovered we must not have consumed any tokens since the last choice point, ie we only peeked at the stream.

Other errors are signaled using the ParseError exception or even arbitrary exceptions.
