Problem Statement/Rationale

If we create a struct which will be used as a collection generic type, and we set the '#[serde(serialize_with = "serialize_object_id_as_hex_string")]' serde helper for the '_id' field (or an other ObjectId field). Then we can not query that field with an ObjectId only with its hex representation.
 

Steps to Reproduce

Consider the following struct:

pub struct User {
  #[serde(serialize_with = "serialize_object_id_as_hex_string")]
  pub _id: ObjectId,
  pub email: String,
  pub password: String,
  pub username: String,
}

Now, if try to query a collection using this as the generic type, then query will not give any result:

let id = ObjectId::from_str(&id)let filter = doc!{"_id": ObjectId::from};
{{ let update = doc!{"$set": {"confirmed": true}};}}

users_coll.update_one(filter, update, None).await
  .map_err(|_| ErrorInternalServerError(""))?;
