README
Deepcopier
This package is meant to make copying of structs to/from others structs a bit easier.
Installation
go get -u github.com/ulule/deepcopier
Usage
// Deep copy instance1 into instance2
Copy(instance1).To(instance2)
// Deep copy instance1 into instance2 and passes the following context (which
// is basically a map[string]interface{}) as first argument
// to methods of instance2 that defined the struct tag "context".
Copy(instance1).WithContext(map[string]interface{}{"foo": "bar"}).To(instance2)
// Deep copy instance2 into instance1
Copy(instance1).From(instance2)
// Deep copy instance2 into instance1 and passes the following context (which
// is basically a map[string]interface{}) as first argument
// to methods of instance1 that defined the struct tag "context".
Copy(instance1).WithContext(map[string]interface{}{"foo": "bar"}).From(instance2)
Available options for deepcopier
struct tag:
Option | Description |
---|---|
field |
Field or method name in source instance |
skip |
Ignores the field |
context |
Takes a map[string]interface{} as first argument (for methods) |
force |
Set the value of a sql.Null* field (instead of copying the struct) |
Options example:
type Source struct {
Name string
SkipMe string
SQLNullStringToSQLNullString sql.NullString
SQLNullStringToString sql.NullString
}
func (Source) MethodThatTakesContext(c map[string]interface{}) string {
return "whatever"
}
type Destination struct {
FieldWithAnotherNameInSource string `deepcopier:"field:Name"`
SkipMe string `deepcopier:"skip"`
MethodThatTakesContext string `deepcopier:"context"`
SQLNullStringToSQLNullString sql.NullString
SQLNullStringToString string `deepcopier:"force"`
}
Example:
package main
import (
"fmt"
"github.com/ulule/deepcopier"
)
// Model
type User struct {
// Basic string field
Name string
// Deepcopier supports https://golang.org/pkg/database/sql/driver/#Valuer
Email sql.NullString
}
func (u *User) MethodThatTakesContext(ctx map[string]interface{}) string {
// do whatever you want
return "hello from this method"
}
// Resource
type UserResource struct {
DisplayName string `deepcopier:"field:Name"`
SkipMe string `deepcopier:"skip"`
MethodThatTakesContext string `deepcopier:"context"`
Email string `deepcopier:"force"`
}
func main() {
user := &User{
Name: "gilles",
Email: sql.NullString{
Valid: true,
String: "[email protected]",
},
}
resource := &UserResource{}
deepcopier.Copy(user).To(resource)
fmt.Println(resource.DisplayName)
fmt.Println(resource.Email)
}
