    // Required methods
    fn set_graph_meta(

}

Sealed trait for variadic lists of ports.

See the [variadics] crate for the strategy we use to implement variadics in Rust.

Required Associated Types

type Ctx<'a>: Variadic

The [Variadic] return type of Self::make_ctx.

Required Methods

fn set_graph_meta( &self, handoffs: &mut [HandoffData], out_handoff_ids: &mut Vec<HandoffId>, sg_id: SubgraphId, handoffs_are_preds: bool, )

Iteratively/recursively set the graph metadata for each port in this list.

Specifically sets:

• HandoffData::preds and HandoffData::succs in the handoffs slice for the handoffs in this PortList (using pred and/or succ).
• out_handoff_ids will be extended with all the handoff IDs in this PortList.

handoffs_are_preds:

• true: Handoffs are predecessors (inputs) to subgraph sg_id.
• false: Handoffs are successors (outputs) from subgraph sg_id.

fn make_ctx<'a>(&self, handoffs: &'a [HandoffData]) -> Self::Ctx<'a>

Iteratively/recursively construct a Ctx variadic list.

(Note that unlike Self::set_graph_meta, this does not mess with pred/succ handoffs for teeing).

Object Safety

This trait is not object safe.
