<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.
