Struct DialogPolicy 

pub struct DialogPolicy { /* private fields */ }

Simple state-machine dialog policy.

Drives a slot-filling task dialog through greeting → slot collection → confirmation → end.

Example

use scirs2_text::dialog::{DialogPolicy, DialogState, DialogAct};

let mut policy = DialogPolicy::new(vec!["origin".to_string(), "destination".to_string()]);
let mut state = DialogState::new();

let action = policy.next_action(&state);
assert_eq!(action.act, DialogAct::Greet);

Implementations

impl DialogPolicy

pub fn new(required_slots: Vec<String>) -> Self

Create a new DialogPolicy requiring the specified slots.

pub fn state(&self) -> &PolicyState

Current state-machine state.

pub fn next_action(&mut self, dialog_state: &DialogState) -> PolicyAction

Compute the next recommended action given the current dialog_state.

This also advances the internal state machine.

pub fn reset(&mut self)

Reset the policy to its initial state.
