¶
Determine whether a library is empty or not. Built-in types are handles as follow. Use the Empty interface to extend functionality.
A value is empty if:
- 0 for integers of any type (e.g. int, int8...etc)
- 0.0 for floats of any type (e.g. float32, float 64)
- maps without any keys
- arrays with length of zero where each element satisfies its type specific empty criteria

Functions ¶
func IsEmpty ¶
func IsEmpty(any interface{}) bool
IsEmpty returns true is the value is empty, false otherwise.
func IsPresent ¶
func IsPresent(any interface{}) bool
IsPresent returns true if the value is not empty, false otherwise.
func RegisterHandler ¶
RegisterHandler registers a particular type to a function that determines whether a value of that type is empty. Useful for types that are in other libraries. However please consider using the EmptyValue interface wherever possible.
func TimeIsEmpty ¶
func TimeIsEmpty(any interface{}) bool
TimeIsEmpty determines whether time.Time object is empty
