Package logger implements a multi-output leveled logger.
|
|
|
|
Other packages use tagged logger to send log messages to shared
|
|
(process-wide) logging engine. The shared logging engine dispatches to
|
|
multiple log systems. The log level can be set separately per log
|
|
system.
|
|
|
|
Logging is asynchronous and does not block the caller. Message
|
|
formatting is performed by the caller goroutine to avoid incorrect
|
|
logging of mutable state.
