Changes

Version 1.3.5

  • Add optional support for conduit and resourcet.

Version 1.3.4

  • Fix typo in unliftio-core Cabal flag.

Version 1.3.3

  • Add MonadBase, MonadBaseControl, PrimMonad and MonadSafe instances for DiT.

  • Add Cabal flags for optional third-party libraries support: monad-control, pipes, pipes-safe, primitive, streaming, transformers-base, unliftio-core.

Version 1.3.2

  • Add MonadUnliftIO instance for DiT.

  • Add MonadDi instance for streaming’s Stream.

Version 1.3.1

  • Add MonadError instance for DiT.

Version 1.3

  • The MonadThrow instance for DiT doesn’t log exceptions automatically any more. This is because otherwise catching and re-throwing exceptions in downstream code, by default, ends up logging the same exception more than once.

  • A throw function behaving as the previous MonadThrow instance for DiT was introduced.

  • Documentation improvements.

Version 1.2

  • The MonadMask constraint added in Version 1.1 is gone, effecively undoing the breaking change introduced in Version 1.1.

Version 1.1

  • BREAKING CHANGE: The MonadThrow instance for DiT level path msg m instance now relies on Di.Core.throw, potentially logging exceptions at the throw site. This introduces a new MonadMask m instance constraint which can’t be satisfied by STM. There is a DiT level path msg STM instance that skips logging exceptions (which is the only sensible behavior, anyway). However, if your m is not exactly STM but some wrapper around it, you will need to provide a MonadThrow instance manually or use Di.Core.throw' directly. On the other hand, satisfying this MonadMask constraint should be easy for monads that can run IO.

  • Added onException.

Version 1.0.2

  • Backwards compatibility with mtl < 2.2.2.

Version 1.0.1

  • Backwards compatibility with transformers < 0.5.3.

Version 1.0

  • This is a new library part of the di-core ecosystem. Consider this first release of the new ecosystem a preview release: The API is likely to stay stable, but extensive testing, formalization and tooling is due.
