# a library to create type dynamically

[![Report](https://goreportcard.com/badge/github.com/xiaoxin01/typeregistry)](https://goreportcard.com/badge/github.com/xiaoxin01/typeregistry)

## how to use

```go

// 1. define struct

type Student struct {

	Age  int

	Name string

}

// 2. add reflect type

key := AddType(new(Student))

// 3. create struct from registed key

student := Make(key)

```

## custom registed key

```go

var i interface{} = new(Student)

// use lowercase struct name as key

name := AddTypeWithKey(i, func(i interface{}) string {

	tpe := reflect.TypeOf(i).Elem()

	return strings.ToLower(tpe.Name())

})

student, ok := Create("student").(*Student)

```
