DeviceGraphNode

struct DeviceGraphNode[arena_origin: ImmutOrigin]

A handle to a node in an under-construction device graph.

Returned by node-adding methods on DeviceGraphBuilder such as add_function, add_copy, and add_memset. The handle can be used to refer to the node from later API calls (for example, when expressing explicit dependency edges).

Parameters​

  • ​arena_origin (ImmutOrigin): Origin of the DeviceGraph.create scope that produced this handle. Branding ties the handle's usability to that scope, so a node cannot be used outside the builder callback or mixed into a different graph.

Fields​

  • ​id (Int32): Opaque integer identifier of the node within its graph builder.

Implemented traits​

AnyType, Copyable, ImplicitlyCopyable, ImplicitlyDeletable, Movable, RegisterPassable, TrivialRegisterPassable, Writable

Methods​

write_to​

def write_to(self, mut writer: T)

Writes a human-readable representation of this node handle.

Args:

  • ​writer (T): The writer to output to.
