Functions

func DefaultPath

func DefaultPath() string

DefaultPath returns the default path that will be used. This will use cmdline.AppIdentifier (if set) to better isolate the log location.

func MaxBackups

func MaxBackups(maxBackups int) func(*Rotator) error

MaxBackups sets the maximum number of old log files to retain. Defaults to DefaultMaxBackups.

func MaxSize

func MaxSize(maxSize int64) func(*Rotator) error

MaxSize sets the maximum size of the log file before it gets rotated. Defaults to DefaultMaxSize.

func Path

func Path(path string) func(*Rotator) error

Path specifies the file to write logs to. Backup log files will be retained in the same directory. Defaults to the value of DefaultPath().

Types

type Rotator

type Rotator struct {
	// contains filtered or unexported fields
}

Rotator holds the rotator data.

func New

func New(options ...func(*Rotator) error) (*Rotator, error)

New creates a new Rotator with the specified options.

func (*Rotator) Close

func (r *Rotator) Close() error

Close implements io.Closer.

func (*Rotator) Write

func (r *Rotator) Write(b []byte) (int, error)
