defmodule SimpleshopTheme.Accounts.Scope do

@moduledoc """
|
|
Defines the scope of the caller to be used throughout the app.
|
|
|
|
The `SimpleshopTheme.Accounts.Scope` allows public interfaces to receive
|
|
information about the caller, such as if the call is initiated from an
|
|
end-user, and if so, which user. Additionally, such a scope can carry fields
|
|
such as "super user" or other privileges for use as authorization, or to
|
|
ensure specific code paths can only be access for a given scope.
|
|
|
|
It is useful for logging as well as for scoping pubsub subscriptions and
|
|
broadcasts when a caller subscribes to an interface or performs a particular
|
|
action.
|
|
|
|
Feel free to extend the fields on this struct to fit the needs of
|
|
growing application requirements.
