	<brief_description>
		A handle for a [Resource]'s unique identifier.
	</brief_description>
	<description>
		The RID [Variant] type is used to access a low-level resource by its unique ID. RIDs are opaque, which means they do not grant access to the resource by themselves. They are used by the low-level server classes, such as [DisplayServer], [RenderingServer], [TextServer], etc.
		A low-level resource may correspond to a high-level [Resource], such as [Texture] or [Mesh].
		[b]Note:[/b] RIDs are only useful during the current session. It won't correspond to a similar resource if sent over a network, or loaded from a file at a later time.
		[b]Note:[/b] In a boolean context, an RID will evaluate to [code]false[/code] if it has the invalid ID [code]0[/code]. Otherwise, an RID will always evaluate to [code]true[/code]. This is equivalent to calling [method is_valid].
