Error when using insert_one()

Error when using function collection.insert_one().

Code:

module sublib

import mongo

fn main() {
	mongo_uri := mongo.uri_new('xxx')
	client := mongo_uri.get_database('discord_bot')
	col := client.get_collection('discord_bot', 'user_data')

	col.insert_one({
		'str': 'string'
		'number': 2
		'float': 2.1
		'boolean': true
	})

	response := col.find({
		'str': 'string'
	}).lean()

	assert response[0].as_map()['str'] or { 0 }.str() == 'string'
}

Error:

C:/Users/xxx/.vmodules/mongo/src/collection.v:36:75: error: cannot use `&&C.bson_t` as `&C.bson_t` in argument 4 to `C.mongoc_collection_insert_one`
   34 |     reply := new_bson()
   35 | 
   36 |     result := C.mongoc_collection_insert_one(collection, document_bson_t, 0, &reply, &error)
      |                                                                              ~~~~~~
   37 |     unsafe { println(C.bson_as_json(&reply, 0).vstring()) }
   38 |     if unsafe { error.message.vstring() != '' } {

I've already updated V and Mongo-V. Hopefully this question is adequately formatted.

Running the example

I am newbe to V, trying to run the exemple I get the following :
" error: cannot use &string as &char in argument 2 to C.bson_oid_to_string "

Design and Planning

This issue is to discuss the planning of the mongo vlang driver.

Currently the implementation is a wrapper around the mongo-c-driver. Is it the long term solution?
Are we planning to develop a native vlang driver? Like mongo-go-driver?
Even if we keep the wrapping the mongo-c-driver, do we want a vlang native bson library? Similar to https://github.com/mongodb/mongo-go-driver/tree/master/bson
How to handler marshal and unmarshal between bson and vlang struct?

Check out my solution

Hey,
I've already wrote some code for mongo on VLang
You can check it out here https://github.com/Chank1e/mongov

Would be great if I can help you with this piece of code)

Can't run find

I'm having trouble doing a basic find.

query := mongo.new_from_json('{}')
count := collection.count_documents(query)
println(count) // 69 return ok

bson_doc := mongo.new_bson()
cursor := collection.find(query)

for cursor.next(&bson_doc) {
   str := mongo.as_canonical_extended_json(bson_doc)
   println(str)
}

it returns me the following error:

mongo.v:19:20: error: unknown function: mongo.as_canonical_extended_json
   17 | 
   18 |      for cursor.next(&bson_doc) {
   19 |       str := mongo.as_canonical_extended_json(bson_doc)
      |                    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   20 |       println(str)
   21 |     }

can't run the example

I am having an issue running the example
