问题 I have some questions regarding the capabilities regarding Azure Queues, Functions, and Workers. I'm not really sure how this works. Scenario: q-notifications is an queue in an Azure storage account. f-process-notification is a function in Azure that is bound to q-notifications.

That is, if I tag my test functions with #[test] but not #

问题 Previously ORM's i've used have mapped database columns directly to class properties which allowed you to specific property visibility, just as you normally would to restrict access to certain properties e.g. passwords.

My desire is to restrict the scope of access to a user password to only the object i.e. private. Setting a class property with
