pointer

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 Bool ¶

func Bool(b bool) *bool

Bool returns a pointer to a bool.

func BoolDeref ¶

func BoolDeref(ptr *bool, def bool) bool

BoolDeref dereferences the bool ptr and returns it if not nil, or else returns def.

func BoolEqual ¶

func BoolEqual(a, b *bool) bool

BoolEqual returns true if both arguments are nil or both arguments dereference to the same value.

func Float32 ¶

func Float32(i float32) *float32

Float32 returns a pointer to the a float32.

func Float32Deref ¶

func Float32Deref(ptr *float32, def float32) float32

Float32Deref dereferences the float32 ptr and returns it if not nil, or else returns def.

func Float32Equal ¶

func Float32Equal(a, b *float32) bool

Float32Equal returns true if both arguments are nil or both arguments dereference to the same value.

func Float64 ¶

func Float64(i float64) *float64

Float64 returns a pointer to the a float64.

func Float64Deref ¶

func Float64Deref(ptr *float64, def float64) float64

Float64Deref dereferences the float64 ptr and returns it if not nil, or else returns def.

func Float64Equal ¶

func Float64Equal(a, b *float64) bool

Float64Equal returns true if both arguments are nil or both arguments dereference to the same value.

func Int ¶

func Int(i int) *int

Int returns a pointer to an int

func Int32 ¶

func Int32(i int32) *int32

Int32 returns a pointer to an int32.

func Int32Deref ¶

func Int32Deref(ptr *int32, def int32) int32

Int32Deref dereferences the int32 ptr and returns it if not nil, or else returns def.

func Int32Equal ¶

func Int32Equal(a, b *int32) bool

Int32Equal returns true if both arguments are nil or both arguments dereference to the same value.

func Int64 ¶

func Int64(i int64) *int64

Int64 returns a pointer to an int64.

func Int64Deref ¶

func Int64Deref(ptr *int64, def int64) int64

Int64Deref dereferences the int64 ptr and returns it if not nil, or else returns def.

func Int64Equal ¶

func Int64Equal(a, b *int64) bool

Int64Equal returns true if both arguments are nil or both arguments dereference to the same value.

func IntDeref ¶

func IntDeref(ptr *int, def int) int

IntDeref dereferences the int ptr and returns it if not nil, or else returns def.

func String ¶

func String(s string) *string

String returns a pointer to a string.

func StringDeref ¶

func StringDeref(ptr *string, def string) string

StringDeref dereferences the string ptr and returns it if not nil, or else returns def.

func StringEqual ¶

func StringEqual(a, b *string) bool

StringEqual returns true if both arguments are nil or both arguments dereference to the same value.
