sqlx里面如何操作 in ？

sqlx里面的in操作，还是相对比较特殊的，怎么来实现呢？直接上代码，供参考：

package main

import ( "fmt"

_ "github.com/go-sql-driver/mysql"
"github.com/jmoiron/sqlx"

)

type Hoge struct { ID int db:"id" Name string db:"name" }

func main() { db, err := connect() if err != nil { panic(err) }

s := "SELECT * FROM hoge WHERE id IN (?)"
q, vs, err := sqlx.In(s, []int{2, 3})
// fmt.Printf("%+v\n", q)
// => SELECT * FROM hoge WHERE id IN (?, ?)
if err != nil {
    panic(err)
}

var hs []Hoge
err = db.Select(&hs, q, vs...)
if err != nil {
    panic(err)
}

fmt.Printf("%+v\n", hs)
// => [{ID:2 Name:fuga} {ID:3 Name:piyo}]

}

func connect() (*sqlx.DB, error) { return sqlx.Connect( "mysql", fmt.Sprintf( "%s:%s@tcp(%s:%s)/%s", "root", "", "localhost", "3306", "test", ), ) }
