Functions ¶
func ArrayIsZero ¶
func ArrayIsZerov ¶
func CanConvert ¶
CanConvert reports whether the value v can be converted to type t. If v.CanConvert(t) returns true then v.Convert(t) will not panic.
func CanConvertHelper ¶
CanConvertHelper is a shorthand of CanConvert.
func HasStringer ¶
func IsExported ¶
func IsExported(f *reflect.StructField) bool
IsExported reports whether the field is exported.
func IsNil ¶
IsNil for go1.12+, the difference is it never panic on unavailable kinds. see also reflect.IsNil.
func IsNilv ¶
IsNilv for go1.12+, the difference is it never panic on unavailable kinds. see also reflect.IsNil.
func IsNumComplexKind ¶
func IsNumFloatKind ¶
func IsNumIntegerKind ¶
func IsNumIntegerType ¶
func IsNumSIntegerKind ¶
func IsNumUIntegerKind ¶
func IsNumericKind ¶
func IsNumericType ¶
func IsZero ¶
IsZero for go1.12+, the difference is it never panic on unavailable kinds. see also reflect.IsZero.
func IsZerov ¶
IsZerov for go1.12+, the difference is it never panic on unavailable kinds. see also reflect.IsZero.
func Iserrortype ¶
func Rdecode ¶
Rdecode decodes an interface{} or a pointer to something to its underlying data type.
Suppose we have an interface{} pointer Value which stored a pointer to an integer, Rdecode will extract or retrieve the Value of that integer.
See our TestRdecode() in ref_test.go
var b = 11
var i interface{} = &b
var v = reflect.ValueOf(&i)
var n = Rdecode(v)
println(n.Type()) // = int
`prev` returns the previous Value before we arrived at the final `ret` Value. In another word, the value of `prev` Value is a pointer which points to the value of `ret` Value. Or, it's a interface{} wrapped about `ret`.
A interface{} will be unboxed to its underlying datatype after Rdecode invoked.
func Rdecodesimple ¶
Rdecodesimple is a shortcut to Rdecode without `prev` returned.
func Rdecodetype ¶
Rdecodetype try to strip off ptr and interface{} from a type.
It might not work properly on some cases because interface{} cannot be stripped with calling typ.Elem().
In this case, use rdecodesimple(value).Type() instead of Rdecodetypesimple(value.Type()).
func Rdecodetypesimple ¶
Rdecodetypesimple try to strip off ptr and interface{} from a type.
It might not work properly on some cases because interface{} cannot be stripped with calling typ.Elem(). For this case, use Rdecodesimple(value).Type() instead of Rdecodetypesimple(value.Type()).
func SliceAppend ¶
SliceAppend combines all given slices ('vv') as one result slice. That is, SliceAppend([]int{1,2}, []int{2,3}) will return []int{1,2,2,3}.
func SliceMerge ¶
SliceMerge merge all given slices ('vv') as one result slice. That is, SliceAppend([]int{1,2}, []int{2,3}) will return []int{1,2,3}.
func StructIsZero ¶
func StructIsZerov ¶
func Typfmtvlite ¶
func ValfmtPure ¶
func ValfmtptrPure ¶
ValfmtptrPure will step into a ptr value at first, then Valfmt.
