+Initialize structs with default values
+
+- Supports almost all kind of types
+  - Scalar types
+    - `int/8/16/32/64`, `uint/8/16/32/64`, `float32/64`
+    - `uintptr`, `bool`, `string`
+  - Complex types
+    - `map`, `slice`, `struct`
+  - Aliased types
+    - `time.Duration`
+    - e.g., `type Enum string`
+  - Pointer types
+    - e.g., `*SampleStruct`, `*int`
+- Recursively initializes fields in a struct
+- Dynamically sets default values by [`defaults.Setter`](./setter.go) interface
+- Preserves non-initial values from being reset with a default value
+
+
+Usage

+	Age    int    `default:"27"`

+
+	Slice       []string       `default:"[]"`
+	SliceByJSON []int          `default:"[1, 2, 3]"` // Supports JSON
+
+	Map                 map[string]int `default:"{}"`
+	MapByJSON           map[string]int `default:"{\"foo\": 123}"`
+	MapOfStruct         map[string]OtherStruct
+	MapOfPtrStruct      map[string]*OtherStruct
+	MapOfStructWithTag  map[string]OtherStruct `default:"{\"Key1\": {\"Foo\":123}}"`
+    
+	Struct    OtherStruct  `default:"{}"`
+	StructPtr *OtherStruct `default:"{\"Foo\": 123}"`
+
+	NoTag  OtherStruct               // Recurses into a nested struct by default
+	OptOut OtherStruct `default:"-"` // Opt-out
+}
+
+type OtherStruct struct {
+	Hello  string `default:"world"` // Tags in a nested struct also work
+	Foo    int    `default:"-"`
+	Random int    `default:"-"`
+}
+
+// SetDefaults implements defaults.Setter interface
+func (s *OtherStruct) SetDefaults() {
+	if defaults.CanUpdate(s.Random) { // Check if it's a zero value (recommended)
