Changes
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.
