Types

type Mask

type Mask byte

Mask represents a log severity mask See POSIX.1-2008. Also see POSIX.1-2001, RFC 3164, and RFC 5424.

const (
	Emerg   Mask = (1 << pri.Emerg)
	Alert   Mask = (1 << pri.Alert)
	Crit    Mask = (1 << pri.Crit)
	Err     Mask = (1 << pri.Err)
	Warning Mask = (1 << pri.Warning)
	Notice  Mask = (1 << pri.Notice)
	Info    Mask = (1 << pri.Info)
	Debug   Mask = (1 << pri.Debug)
)
