Functions

func IsEmpty

func IsEmpty(value interface{}) bool

IsEmpty checks whether given <value> empty. It returns true if <value> is in: 0, nil, false, "", len(slice/map/chan) == 0, or else it returns false.

func IsNil

func IsNil(value interface{}, traceSource ...bool) bool

IsNil checks whether given <value> is nil. Parameter <traceSource> is used for tracing to the source variable if given <value> is type of a pinter that also points to a pointer. It returns nil if the source is nil when <traceSource> is true. Note that it might use reflect feature which affects performance a little bit.
