Functions ¶

func RegisterAdapter ¶

func RegisterAdapter(adapter Adapter)

RegisterAdapter registers an Adapter to be used by ConvertLogger.

Types ¶

type Adapter ¶

type Adapter interface {
	Convert(backend interface{}) Logger
}

Adapter defines an adapter to convert a logger to Logger.

type Level ¶

type Level = internal.Level

Level is used to define severity of messages to be reported.

func ParseLogLevel ¶

func ParseLogLevel(in string) (Level, error)

ParseLogLevel parses incoming string into a Level and returns LevelUndefined with an error if an unknown logging level was passed.

type Logger ¶

type Logger = internal.Logger

Logger is the interface of a logger provided by an extended context.

This is the complete logger with all the required methods/features.

func ConvertLogger ¶

func ConvertLogger(logger interface{}) Logger

ConvertLogger converts arbitrary logger to Logger. If it was unable to then it returns a nil.

To enable logadapter-s for this converter add imports, for example:

import _ "github.com/facebookincubator/contest/pkg/xcontext/logger/logadapter/logrus"
import _ "github.com/facebookincubator/contest/pkg/xcontext/logger/logadapter/zap"

func Dummy ¶

func Dummy() Logger

Dummy returns a dummy logger which implements Logger, but does nothing.

type MinimalLogger ¶

type MinimalLogger = internal.MinimalLogger

MinimalLogger is the interfaces of a logger without contextual methods.
