Module sink

Provides sinks to flexibly output log messages to specified targets.

Sink

Sinks are the objects that actually write logs to their targets. Each sink should be responsible for only single target (e.g file, console, database), and each sink has its own private instance of Formatter object.

A sink has its own level filter that is not shared with the logger, and a Logger can combine multiple Sinks.

Combined sink

A combined sink is also a sink, but instead of having its own target and formatter, it combines other sinks (as sub-sinks).

Operations on a combined sink will be forwarded to its sub-sinks according to the implementation.
