Variables

var Level = 0

Level controls which verbose logging statements are executed. It is the minimal number for which V(x) returns true.

Types

type Verbose

type Verbose bool

Verbose is a boolean type that implements info log methods. See V().

func V

func V(x int) Verbose

V reports whether verbosity at the call site is at least the requested level. The returned value is a boolean of type Verbose, which implements Printf. This method will write to the log if called. Whether an individual call to V generates a log record depends on the setting of Level.

func (Verbose) Printf

func (v Verbose) Printf(format string, values ...interface{})

Printf is equivalent to log.Printf, guarded by the value of v.
