Hide fields

Hide fields in go stucture by tag 'hide'

Supported types

int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, float32, float64, complex64, complex128, bool, string

array, slice, map

Please note:

• that complex64 will hide by default type value only
• not hide if field value equal default type value
• be careful with pointers cause this method mutate structure values
• Doesn't support interfaces

how to

type t struct {
	Int         int               `hide:"-1"`
	Uint        uint              `hide:"-1"`
	str         string            `hide:"**"`
	Slice       []string          `hide:"**"`
	Map         map[string]string `hide:"**"`
}

v := t{
	 Int:   1,
	 Uint:  2,
	 str:   "string",
	 Slice: []string{"one", "", "three"},
	 Map:   map[string]string{"key": "value"},
}

HideFields(&v)

// the resust is v with hid values
{
Int:   -1,
Uint:  0, // cause "-1" is not valid value for this type 
str:   "**",
Slice: []string{"**", "", "**"},
Map:   map[string]string{"key": "**"},
}
