Struct Ctx 

pub struct Ctx<'a> {
    pub device: Option<&'a Device>,
}

What a node knows beyond its input, which travels separately. A type rather than an argument because it is the channel: adding to it is additive, and every node ever written has this signature.

Fields

device: Option<&'a Device>

Where this node was said to run, if it was said. It arrives as information: the core cannot move anything to a GPU, so the one that obeys is the node.
