Struct Command 

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

Fluent builder for what a node returns: state delta + routing + optional payload.

Implementations

impl<S: GraphState> Command<S>

pub fn new(update: S::Update) -> Self

Build a Command with a state delta. Default routing is Goto::End.

pub fn goto_only(goto: Goto) -> Self

where S::Update: Default,

Build with default state delta and a custom goto.

pub fn goto(self, name: impl Into<String>) -> Self

Route to a single named node.

pub fn goto_multiple<I, N>(self, names: I) -> Self

where I: IntoIterator<Item = N>, N: Into<String>,

Fan out to multiple named nodes.

pub fn send<I, N>(self, targets: I) -> Self

where I: IntoIterator<Item = (N, Value)>, N: Into<String>,

Dispatch with per-target payloads (Goto::Send).

pub fn end(self) -> Self

Terminate the graph.

pub fn with_payload(self, payload: Value) -> Self

Attach a payload. If the goto is a single-target Goto::Node, this promotes it to Goto::Send so the receiving node can read the payload. On Goto::End the payload is dropped.

Trait Implementations

impl<S: Clone + GraphState> Clone for Command<S>

where S::Update: Clone,

fn clone(&self) -> Command<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug + GraphState> Debug for Command<S>

where S::Update: Debug,

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

Formats the value using the given formatter.

impl<S: GraphState> From<Command<S>> for NodeOut<S>

fn from(c: Command<S>) -> Self

Converts to this type from the input type.
