Specs

fetch(module :: module(), id :: BSON.ObjectId.t(), opts :: Keyword.t()) ::
  {:ok, Mongo.Collection.t()} | {:error, :not_found} | {:error, any()}

Returns a single document struct for the collection defined in the given module and bson object id as a tuple of {:ok, document}.

Returns {:error, :not_found} if no result was found.

If multiple documents satisfy the query, this method returns the first document according to the natural order which reflects the order of documents on the disk.
