synopsis:            Structured messages support in co-log ecosystem.
description:

   The library implements of a very simple approach to structured logging, that
   ca be used with the [co-log](https://hackage.haskell.org/package/co-log)
   ecosystem or on it's own see [cheops-logger](https://github.com/cheopslab/cheops-logger).
   .
   It provides:
   .
     * "Colog.Json" — API for adding structured context to the log messages
     * "Colog.Json.Action" — efficient function for dumping logs in the 
       following format.
   .
   By default it emits logs in the following format (pretty-printed for convenience):
   .
   @
   { "namespace":"server.package" -- namespace for the component
   , "severity": \"DEBUG\"          -- severity level
   , "thread":19                  -- id of the thread that emitted the message
   , "message":"some long text "  -- textual message itself
   , "data":                      -- user data
      { "ip":"8.8.8.8"
      , "http.request_id":"b362cd5db5c193c05312af4d3a399955"
      , "http.method":\"DELETE\"
      , "http.path":"\/url\/"
      , "user_id":"123"
      } 
   }
   @
   .
   The most interesting thing here is the field @data@ that can be used by the user
   to add additional structured info to the message.
