How to write a generic handler in Go?

I need to create a HTTP Handler for a REST API.

This REST API have many different objects that are stored in a database (MongoDB in my case).

Currently, I need to write one handler per action per object.

I would like to find a way like it's possible with Generics to write a generic handler that could handle a specific action but for any kind of object (As basically it's just CRUD in most of the case)

How can I do this ?

Here is examples of Handlers I would like to transform into a generic one :

func IngredientIndex(w http.ResponseWriter, r *http.Request) {    w.Header().Set("Content-Type", "application/json; charset=UTF-8")    db := r.Context().Value("Database").(*mgo.Database)    ingredients := []data.Ingredient{}    err := db.C("ingredients").Find(bson.M{}).All(&ingredients)    if err != nil {        panic(err)    }    json.NewEncoder(w).Encode(ingredients)}func IngredientGet(w http.ResponseWriter, r *http.Request) {    w.Header().Set("Content-Type", "application/json; charset=UTF-8")    vars := mux.Vars(r)    logger := r.Context().Value("Logger").(zap.Logger)    db := r.Context().Value("Database").(*mgo.Database)    ingredient := data.Ingredient{}    err := db.C("ingredients").Find(bson.M{"_id": bson.ObjectIdHex(vars["id"])}).One(&ingredient)    if err != nil {        w.WriteHeader(404)        logger.Info("Fail to find entity", zap.Error(err))    } else {        json.NewEncoder(w).Encode(ingredient)    }}

Basically I would need a handler like this (This is my tentative that doesn't work) :

func ObjectIndex(collection string, container interface{}) func(http.ResponseWriter, *http.Request) {    return func(w http.ResponseWriter, r *http.Request) {        w.Header().Set("Content-Type", "application/json; charset=UTF-8")        db := r.Context().Value("Database").(*mgo.Database)        objects := container        err := db.C(collection).Find(bson.M{}).All(&objects)        if err != nil {            panic(err)        }        json.NewEncoder(w).Encode(objects)    }

How can I do that ?
