Struct ConversationManager

pub struct ConversationManager { /* private fields */ }

Data structure allowing the management of conversations and main input to the dialogue model. It contains a HashMap of conversations with UUID keys

Implementations

impl ConversationManager

pub fn new() -> ConversationManager

Build a new ConversationManager

Example

use rust_bert::pipelines::conversation::ConversationManager;

let conversation_manager = ConversationManager::new();

pub fn get_active_conversations( &mut self, ) -> (Vec<&Uuid>, Vec<&mut Conversation>)

Returns a list of the active conversations (containing new inputs to be processed by the model)

Returns

• (Vec<&Uuid>, Vec<&mut Conversation>) Tuple of vectors with the active UUID and Conversations

Example

use rust_bert::pipelines::conversation::{Conversation, ConversationManager};

let mut conversation_manager = ConversationManager::new();

let conversation = Conversation::new("Hi there!");
let empty_conversation = Conversation::new_empty();
let conversation_id = conversation_manager.add(conversation);
let empty_conversation_id = conversation_manager.add(empty_conversation);

let active_conversations = conversation_manager.get_active_conversations();
assert_eq!(active_conversations.0.len(), 1usize);

pub fn get(&mut self, uuid: &Uuid) -> Option<&mut Conversation>

Returns a mutable reference to the conversation wih the provided UUID

Arguments

• uuid - &Uuid of the conversation to retrieve

Returns

• Option<&mut Conversation> Optional mutable reference to the conversation matching the UUID provided

Example

use rust_bert::pipelines::conversation::{Conversation, ConversationManager};

let mut conversation_manager = ConversationManager::new();

let conversation = Conversation::new("Hi there!");
let conversation_id = conversation_manager.add(conversation);

let conversation_ref = conversation_manager.get(&conversation_id);

pub fn get_all(&mut self) -> HashMap<&Uuid, &Conversation>

Returns a HashMap containing references to all conversations stored in the manager

Example

use rust_bert::pipelines::conversation::{Conversation, ConversationManager};

let mut conversation_manager = ConversationManager::new();

let conversation = Conversation::new("Hi there!");
let conversation_id = conversation_manager.add(conversation);

let all_conversations = conversation_manager.get_all();

pub fn create(&mut self, text: &str) -> Uuid

Creates a conversation and add it to the conversation manager

Arguments

• text - &str string slice with an original user input

Returns

• Uuid for the conversation created

Example

use rust_bert::pipelines::conversation::{Conversation, ConversationManager};

let mut conversation_manager = ConversationManager::new();

let conversation_id = conversation_manager.create("Hi there!");

pub fn create_empty(&mut self) -> Uuid

Creates an empty conversation and add it to the conversation manager

Returns

• Uuid for the conversation created

Example

use rust_bert::pipelines::conversation::{Conversation, ConversationManager};

let mut conversation_manager = ConversationManager::new();

let conversation_id = conversation_manager.create_empty();

pub fn add(&mut self, conversation: Conversation) -> Uuid

Adds an existing conversation to the conversation manager

Arguments

• conversation - Conversation to be added to the conversation manager

Returns

• Uuid for the conversation created

Example

use rust_bert::pipelines::conversation::{Conversation, ConversationManager};

let mut conversation_manager = ConversationManager::new();

let conversation = Conversation::new("Hi there!");
let conversation_id = conversation_manager.add(conversation);

pub fn remove(&mut self, uuid: &Uuid) -> Option<Conversation>

Deregister a conversation from the conversation manager

Arguments

• uuid - &Uuid of the conversation to deregister from the conversation manager

Returns

• Option<Conversation> de-registered conversation

Example

use rust_bert::pipelines::conversation::{Conversation, ConversationManager};

let mut conversation_manager = ConversationManager::new();

let conversation_id = conversation_manager.create("Hi there!");
conversation_manager.remove(&conversation_id);

pub fn clear(&mut self) -> HashMap<Uuid, Conversation>

Clear all conversations from the conversation manager, and returns the conversations and their former UUID.

Returns

• HashMap<Uuid, Conversation> de-registered conversations

Example

use rust_bert::pipelines::conversation::{Conversation, ConversationManager};

let mut conversation_manager = ConversationManager::new();

let conversation_id = conversation_manager.create("Hi there!");
let conversations = conversation_manager.clear();
