Method add_kernel_node

crates/cust/src/graph.rs:375–398

Adds a kernel invocation node to this graph, [`KernelInvocation`] can be created using [`kernel_invocation`] which uses the same syntax as [`launch`](crate::launch). This will place the node after its dependencies (which will execute before it).

        invocation: KernelInvocation,
        dependencies: impl AsRef<[GraphNode]>,
