Types

type Logger

type Logger interface {
	Debug(msg string, keyvals ...interface{})
	Info(msg string, keyvals ...interface{})
	Warn(msg string, keyvals ...interface{})
	Error(err error, keyvals ...interface{})
	Fatal(err error, keyvalls ...interface{})
	Bug(err error, keyvalls ...interface{})
	With(args ...interface{}) Logger
}

Logger is the fundamental interface for all log operations. Logger creates a log event from keyvals, a variadic sequence of alternating keys and values.

Implementations must be safe for concurrent use by multiple goroutines. In particular, any implementation of Logger that appends to keyvals or modifies or retains any of its elements must make a copy first.
