Types

type BasicT 

type BasicT interface {
	// Tracef formats message according to format specifier
	// and writes to log with level Trace.
	Tracef(format string, params ...interface{})

	// Debugf formats message according to format specifier
	// and writes to log with level Debug.
	Debugf(format string, params ...interface{})

	// Infof formats message according to format specifier
	// and writes to log with level Info.
	Infof(format string, params ...interface{})

	// Warnf formats message according to format specifier
	// and writes to log with level Warn.
	Warnf(format string, params ...interface{}) error

	// Errorf formats message according to format specifier
	// and writes to log with level Error.
	Errorf(format string, params ...interface{}) error

	// Criticalf formats message according to format specifier
	// and writes to log with level Critical.
	Criticalf(format string, params ...interface{}) error

	// Trace formats message using the default formats for its operands
	// and writes to log with level Trace.
	Trace(v ...interface{})

	// Debug formats message using the default formats for its operands
	// and writes to log with level Debug.
	Debug(v ...interface{})

	// Info formats message using the default formats for its operands
	// and writes to log with level Info.
	Info(v ...interface{})

	// Warn formats message using the default formats for its operands
	// and writes to log with level Warn.
	Warn(v ...interface{}) error

	// Error formats message using the default formats for its operands
	// and writes to log with level Error.
	Error(v ...interface{}) error

	// Critical formats message using the default formats for its operands
	// and writes to log with level Critical.
	Critical(v ...interface{}) error

	// Flush flushes all the messages in the logger.
	Flush()

	// Close flushes all the messages in the logger and closes it. The logger cannot be used after this operation.
	Close()
}

BasicT represents structs capable of logging messages. This interface matches seelog.LoggerInterface.

type ContextFormatFilter 

type ContextFormatFilter struct {
	Context []string
}

ContextFormatFilter is a filter that can add a context to the parameters of a log message.

func (ContextFormatFilter) Filter 

func (f ContextFormatFilter) Filter(params ...interface{}) (newParams []interface{})

Filter adds the context at the beginning of the parameter slice.

func (ContextFormatFilter) Filterf 

func (f ContextFormatFilter) Filterf(format string, params ...interface{}) (newFormat string, newParams []interface{})

Filterf adds the context in from of the format string.

type DelegateLogger 

type DelegateLogger struct {
	BaseLoggerInstance BasicT
}

DelegateLogger holds the base logger for logging

type FormatFilter 

type FormatFilter interface {

	// Filter modifies parameters that will be passed to log.Debug, log.Info, etc.
	Filter(params ...interface{}) (newParams []interface{})

	// Filter modifies format and/or parameter strings that will be passed to log.Debugf, log.Infof, etc.
	Filterf(format string, params ...interface{}) (newFormat string, newParams []interface{})
}

FormatFilter can modify the format and or parameters to be passed to a logger.
