Module betterstack.uptime.mixins

This module contains the magic that is the DynamicVariableMixin class. When using this mixin, you can assign variables that track if they get changed, whilst keeping the interface for the user the same. For example:

test = DynamicVariableMixin()
test.add_tracked_property("y", 123)
print(test.y)
test.y = 456
print(test.y)
print(test.get_modified_properties())
