Functions

func AllPtrFieldsNil

func AllPtrFieldsNil(obj interface{}) bool

AllPtrFieldsNil tests whether all pointer fields in a struct are nil. This is useful when, for example, an API struct is handled by plugins which need to distinguish "no plugin accepted this spec" from "this spec is empty".

This function is only valid for structs and pointers to structs. Any other type will cause a panic. Passing a typed nil pointer will return true.

func Int32Ptr

func Int32Ptr(i int32) *int32

Int32Ptr returns a pointer to an int32

func Int32PtrDerefOr

func Int32PtrDerefOr(ptr *int32, def int32) int32

Int32PtrDerefOr dereference the int32 ptr and returns it i not nil, else returns def.
