declaring read-only and write-only properties

[ActualMasterOogway]

How do i declare read-only/write-only properties in a class?
I couldn't find anything on the devforum or in the documentation, is it even possible to do that?

declare class DrawEntry
	Visible: boolean
	Transparency: number
	Opacity: number
	ZIndex: number
	Color: Color3

	function Remove(self): nil
	function Destroy(self): nil
	function MoveToFront(self): nil
	function MoveToBack(self): nil
end

declare class TextDrawing extends DrawEntry
	Text: string
	TextBounds: Vector2 -- read only
	Position: Vector2
	Size: number
	Font: number
	Centered: boolean
	Outlined: boolean
	OutlineColor3: boolean
end

declare class ImageDrawing extends DrawEntry
	Data: string -- write only
	ImageSize: Vector2 -- read only
	Size: Vector2
	Position: Vector2
	Rounding: number
end

It is not possible yet. I think Luau will support it in future. See https://github.com/luau-lang/rfcs/blob/master/docs/syntax-property-access-modifiers.md
