Unreleased

0.6.0 - 2025-01-31

Added

  • Add Combinator::bind_with.
  • Implement Iterator for Parser.

Removed

  • Remove Combinator::bind_default, use Combinator::bind_with instead.
  • Remove Parser::parse, use Parser::next instead.

0.5.0 - 2025-01-28

Added

  • Add trait Digest.
  • Add Input::shift_unchecked.
  • Add AcceptedContext::output.
  • Add combinator::bytes.
  • Add Eat<u8>, Eat<&[u8]>, Eat<&[u8;N]>, Eat<Vec<u8>>.
  • Add take/Take.
  • Add Till<u8>, Till<&[u8]>, Till<&[u8;N]>, Till<Vec<u8>>.
  • Add recur/recur_unchecked/Recur/RecurUnchecked/RecurSetter.
  • Add NoSep.
  • Add Parser::builder.

Changed

  • Instant now take a generic param TextRef instead of a lifetime param.
  • Input now take an additional generic param TextRef instead of a lifetime param.
  • The rest of Input::instant is no longer guaranteed to be non-empty.
  • Input::new will return Input directly instead of an Option.
  • Action will now take an additional generic param Text.
  • AcceptedContext::output will always be a struct instead of a reference.
  • eat will no longer accept usize, use take instead.
  • Rewrite Mul.
  • Combinator::fold now only exists for Combinator<Mul> and will return a Combinator<Mul>.
  • Combinator::fold's fold now take acc as the first param and value as the second param.
  • Parser now take an additional generic param TextRef instead of a lifetime param.
  • Snapshot now take an additional generic param TextRef instead of a lifetime param.

Fixed

  • Combinator::optional now will work properly with empty rest string.

Removed

  • Remove Input::new_unchecked and Input::next.
  • Remove implementation of Action for &mut Action.
  • Remove Eat<&String>. Use Eat<&str> and eat(s.as_str()) instead.
  • Remove eat_unchecked. Use wrap instead.
  • Remove Sep, Fold and InlineFold.

0.4.0 - 2025-01-10

Added

  • Add Combinator::fold.

Changed

  • Combinator::sep now should be used after mul and will return a combinator.

Removed

  • Remove combinator * (repeat, init, fold) syntax for inline fold. Use Combinator::fold instead for better type inference.

  • eat, add and bitor can accept &String.
  • Add When, Prevent, Reject, Optional, Boundary, Prepare, Then, Catch, Finally, Map, Tuple, Bind, BindDefault, Select, Range, Pop.

Changed

  • Make Action::State and Action::Heap become generic params.
  • Provided combinator constructors will return concrete types instead of impl types to retain trait information.
  • Eat and Till are now structs instead of traits.
  • Combinator repetition with Fold will be implemented separately to improve performance and simplify type signature.

Removed

  • Remove Input::shift_unchecked and Input::shift.
  • Remove C! macro.
  • Remove eater and eater_unchecked. Use wrap instead.
  • Remove EatChar, EatStr, EatString, EatUsize. Use Eat<T> instead.
