Logging-Related Types

type Logger = LogEvent -> IO ()

A Logger is any function which responds to log events:

data LogEvent

If there is a Logger in the ConnectionData struct, it will be sporadically called with values of type LogEvent.

Constructors

Fields

• logFunction :: String

Basic Loggers

mmLoggerInfo :: Handle -> Logger

mmLoggerInfo prints which calls are happening and which endpoints are being hit, but without the payloads.

mmLoggerInfoFilter :: (LogEvent -> Bool) -> Handle -> Logger

mmLoggerInfoFilter is the same as mmLoggerInfo but takes a user-defined predicate that it uses to select which events to log before writing them to the provided Handle

mmLoggerDebug :: Handle -> Logger

mmLoggerDebug prints the full data of every logging event to the provided Handle.

mmLoggerDebugFilter :: (LogEvent -> Bool) -> Handle -> Logger

mmLoggerDebugFilter is the same as mmLoggerDebug but takes a user-defined predicate that it uses to select which events to log before writing them to the provided Handle

stderr variants

mmLoggerInfoErr :: Logger

mmLoggerInfoErr prints request/response data without payloads to stderr

mmLoggerInfoFilterErr :: (LogEvent -> Bool) -> Logger

mmLoggerInfoFilterErr takes a user-defined predicate that it uses to select which events to log before logging them to stderr.

mmLoggerDebugErr :: Logger

mmLoggerDebugErr prints the full data of every logging event to stderr.

mmLoggerDebugFilterErr :: (LogEvent -> Bool) -> Logger

mmLoggerDebugFilterErr takes a user-defined predicate that it uses to select which events to log before logging them to stderr.
