Functions

func WriteAt 

func WriteAt(l Structured, lvl Level, msg string, fields ...Field) error

WriteAt is a helper method that checks logger and writes message at given level

Types

type Field 

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

Field stores one structured logging field

func Any 

func Any(key string, value interface{}) Field

Any tries to deduce interface{} underlying type and constructs Field from it. Use of this function is ok only for the sole purpose of not repeating its entire code or parts of it in user's code (when you need to log interface{} types with unknown content). Otherwise please use specialized functions. nolint: gocyclo
