Golang復制版：Copier

Copier 是 Golang 的復制版，它從一個結構復制到了另一個結構。它具有以下特點：

• 如果名字匹配，就從一個場景復制到另一個場景

• 如果方法名和場景名匹配，就從方法復制到場景

• 如果場景名和方法名匹配，就從場景復制到方法

• 從片復制到片

• 從結構復制到片

示例代碼：

import . "github.com/jinzhu/copier"
type User struct {
    Name string
    Role string
    Age  int32}
    func (user *User) DoubleAge() int32 {
        return 2 * user.Age}
        type Employee struct {
            Name
            string
    Age       int32
    DoubleAge int32
    EmployeId int64
    SuperRule string}func (employee *Employee) Role(role string) {
    employee.SuperRule = "Super " + role
}
user := User{Name: "Jinzhu", Age: 18, Role: "Admin"}
employee := Employee{}Copy(&employee, &user)
// employee => Employee{ Name: "Jinzhu",           
// Copy from field
//                       Age: 18,                  
// Copy from field
//                       DoubleAge: 36,            
// Copy from method
//                       EmployeeId: 0,            
// Just ignored
//                       SuperRule: "Super Admin", 
// Copy to method
//                      }
// Copy struct to slice
user := User{Name: "hello", Age: 18, Role: "User"}
employees := []Employee{}Copy(&employees, &user)
// employees => [{hello 18 0 36 Super User}]
// Copy slice to sliceusers := []User{{Name: "Jinzhu", Age: 18, Role: "Admin"}, {Name: "jinzhu 2", Age: 30, Role: "Dev"}}
employees := []Employee{}Copy(&employees, &users)
// employees => [{hello 18 0 36 Super User} 
{Jinzhu 18 0 36 Super Admin} {jinzhu 2 30 0 60 Super Dev}]
