Struct HandoffBuilder 

pub struct HandoffBuilder { /* private fields */ }

Builder for a handoff workflow. Rust analogue of HandoffBuilder.

let workflow = HandoffBuilder::new()
    .participant("triage", triage)
    .participant("billing", billing)
    .initial_agent("triage")
    .add_handoff("triage").to(["billing"])
    .autonomous()
    .build()?;

Implementations

impl HandoffBuilder

pub fn new() -> Self

Create an empty builder.

pub fn participant( self, name: impl Into<String>, agent: Arc<dyn SupportsAgentRun>, ) -> Self

Register a participant by name.

pub fn participants( self, participants: impl IntoIterator<Item = (String, Arc<dyn SupportsAgentRun>)>, ) -> Self

Register several participants as (name, agent) pairs.

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

Designate the entry-point agent that first receives user input.

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

Alias for HandoffBuilder::initial_agent (Python’s set_coordinator).

pub fn add_handoff(self, source: impl Into<String>) -> HandoffEdgeBuilder

Begin a handoff edge from source; complete it with HandoffEdgeBuilder::to.

pub fn interaction_mode(self, mode: HandoffInteractionMode) -> Self

Set the interaction mode.

pub fn autonomous(self) -> Self

Run autonomously (single-shot): complete on the first non-handoff answer.

pub fn with_user_input_request(self) -> Self

Request fresh user input between turns (the default).

pub fn max_iterations(self, limit: usize) -> Self

Cap the number of agent turns per user message (Python’s autonomous turn limit; default 50).

pub fn termination_condition<F>(self, condition: F) -> Self

where F: Fn(&[Message]) -> bool + Send + Sync + 'static,

Set a termination condition evaluated against the conversation.

pub fn request_prompt(self, prompt: impl Into<String>) -> Self

Set the prompt shown when requesting user input.

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

Set the workflow name.

pub fn build(self) -> Result<Workflow>

Validate and build the handoff workflow.

impl Default for HandoffBuilder

fn default() -> Self

Returns the “default value” for a type.
