Struct ParentCommand 

pub struct ParentCommand<S: State> {
    pub command: Command<S>,
    pub source_node: String,
    pub namespace: String,
}

Command wrapper for subgraph-to-parent communication

This wrapper is used as an exception mechanism for subgraph nodes to send commands to their parent graph, along with metadata about the source node and namespace.

Type Parameters

• S - The parent graph’s state type

Fields

• command - The command to send to the parent graph
• source_node - The name of the subgraph node sending this command (for debugging and logging)
• namespace - The subgraph namespace for routing purposes

Fields

command: Command<S>

The command to send to the parent graph

source_node: String

Source node information (for debugging and logging)

namespace: String

Subgraph namespace (for routing)

Implementations

impl<S: State> ParentCommand<S>

pub fn from_subgraph( command: Command<S>, source_node: &str, namespace: &str, ) -> Self

Create a new ParentCommand from a subgraph

Arguments

• command - The command to send to the parent graph
• source_node - The name of the subgraph node sending this command
• namespace - The subgraph namespace for routing
