Polysemy.Log.Effect.LogMetadata
Description
Synopsis
- data LogMetadata msg :: Effect where
- Annotated :: HasCallStack => msg -> LogMetadata msg m ()
- annotated :: HasCallStack => Member (LogMetadata msg) r => msg -> Sem r ()
Documentation
data LogMetadata msg :: Effect where Source #
Internal effect used as an intermediate stage between Log and DataLog, for the purpose
of isolating the metadata annotation task.
The type of metadata is arbitrary and chosen in interpreters, but this exposes a HasCallStack dependency since it's
the primary purpose.
Constructors

annotated :: HasCallStack => Member (LogMetadata msg) r => msg -> Sem r () Source #
