Description
This Version is yet a preview
The logging system consists of four main parts:
The logging front-end are those types and functions that are used to produce log messages in the code. This includes the
LogLevel
type, theLogPolicy
type, theLogLabel
andLogScope
types, theLogFunction
type, and theMonadLog
type class.The abstract
LoggerCtx
is the context through which theLogFunction
delivers log messages to the logger back-end.The formatter is a function for serializing log messages.
The logger back-end is a callback that is invoked by
Logger
on each log messages. The logger back-end applies the formatting function and delivers the log messages to some sink.
The framework allows to combine this components in a modular way. The
front-end types, the Logger
, and the back-end callback are represented
by types or type classes. The formatter exists only as a concept
in the implementation of back-ends. These types and concepts together
form the abstract logger interface that is defined in the module
System.Logger.Types.
The package also provides a concrete Logger that implements these components in the module System.Logger.Logger and System.Logger.Backend.Handle
