MongoDB Schema using Deno or Rust

Question

I'm trying to create a schema in MongoDB using deno_mongo for deno and MongoDB rust dive for rust but I cannot figure out if it is possible.

I want to execute something similar to this in Mongo CLI

db.createCollection('test',{ 
  validator: { 
    $jsonSchema: { 
    bsonType: 'object', 
    required:['field1', 'field2'], 
    properties:{ 
      field1: { 
        bsonType:'string', 
        description:'enter field1'
      }, 
      field2: { 
        bsonType:'string', 
        description:'enter field2'
      }
    }
);

deno_mongo does not support createCollection yet (28 September 2020). As Deno evolves there is most certainly going to be options for this but at not yet at the moment.

I tried to find a way to get the name of the database in use, but actually you can not even do that. With javascript you can only get the db["name"] property but that does not confirm the name from MongoDB. It is the same with createCollection.

There is not a createCollection command but there is db.runCommand() create which is not supported yet.

Also there is a way to run scripts in MongoDB shell which then manipulates your database as you wish.
