Struct Command 

pub struct Command<S: State> { /* private fields */ }

A command returned from a node to control graph flow.

Commands allow nodes to override normal edge-based routing, update state, fan out to multiple nodes, or signal interrupts.

Example

use synaptic_graph::{Command, NodeOutput, MessageState};

async fn my_node(state: MessageState) -> Result<NodeOutput<MessageState>, SynapticError> {
    Ok(NodeOutput::Command(Command::goto("summary")))
}

Implementations

impl<S: State> Command<S>

pub fn goto(node: impl Into<String>) -> Self

Create a command that routes to a specific node.

pub fn goto_with_update(node: impl Into<String>, update: S) -> Self

Create a command that routes to a specific node with a state update.

pub fn send(targets: Vec<Send>) -> Self

Create a command that fans out to multiple nodes (map-reduce).

pub fn update(state: S) -> Self

Create a command that only updates state (no routing override).

pub fn resume(value: Value) -> Self

Create a resume command for continuing from an interrupt.

Pass this as input to graph.invoke() to resume a previously interrupted graph execution.

pub fn end() -> Self

Create a command that ends the graph immediately.

Trait Implementations

impl<S: State> Clone for Command<S>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: State> Debug for Command<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result
