Create a child logger for the packages that the service is calling.

Types ¶
type Logger ¶
type Logger struct {
// contains filtered or unexported fields
}
Logger is the wrapper over the logger and keeps the style. The style is generated randomly.
func (*Logger) Child ¶
Child logger from the parent with its own color style.
When to use it?
For example:
parent, _ := log.New("main", false)
db_log, _ := parent.Child("database")
reply, _ := parent.Child("server")
parent.Info("starting", "security_enabled", true)
db_log.Info("starting")
reply.Info("starting", "port", 443)
// prints the following
// INFO main: starting: security_enabled=true
// INFO main::database: starting
// INFO main::server: starting, port=443
type LoggerStyle ¶
type LoggerStyle struct {
// contains filtered or unexported fields
}
LoggerStyle defines the various colors for each log parts.
