Module: SecureKeys::Core::Console::Argument::Fetchable

Included in:
Handler, Validation::Console::Argument::Scan::Handler
Defined in:
lib/core/console/arguments/fetchable.rb

Overview

Shared fetch/set behaviour for argument handler classes. Include this module inside class << self so the methods become class-level accessors that check the handler’s own arguments hash before falling back to environment variables.

The including class must expose arguments as a class-level reader (via attr_reader :arguments inside class << self).
