Struct ChatView 

pub struct ChatView { /* private fields */ }

A streamed, Markdown transcript with metadata and source chips.

ChatView owns the transcript state and one TextViewState per message, so tokens can be appended without rebuilding the whole document. It emits ChatViewEvent for actions the host must handle.

Implementations

impl ChatView

pub fn new(cx: &mut Context<'_, Self>) -> Self

Create an empty transcript.

pub fn empty_state(self, empty: EmptyState) -> Self

Replace the empty state.

pub fn set_empty_state(&mut self, empty: EmptyState, cx: &mut Context<'_, Self>)

Replace the empty state and redraw.

pub fn state(&self) -> &Entity<ChatState>

The underlying reducer, for hosts that need read access.

pub fn len(&self, cx: &App) -> usize

Number of messages.

pub fn is_empty(&self, cx: &App) -> bool

Returns whether the transcript is empty.

pub fn push_message( &mut self, message: NewMessage, cx: &mut Context<'_, Self>, ) -> MessageId

Append a message and create its render state.

pub fn push_user( &mut self, text: impl Into<String>, cx: &mut Context<'_, Self>, ) -> MessageId

Append a user message.

pub fn push_system( &mut self, text: impl Into<String>, cx: &mut Context<'_, Self>, ) -> MessageId

Append a system notice.

pub fn push_system_before( &mut self, before: MessageId, text: impl Into<String>, cx: &mut Context<'_, Self>, ) -> bool

Insert a system notice immediately before before.

Use this for per-question context notes: the note then appears between the question and the assistant placeholder, exactly where the attached papers belong. Returns false when before is unknown.

pub fn begin_assistant(&mut self, cx: &mut Context<'_, Self>) -> MessageId

Start an empty streaming assistant message.

pub fn append( &mut self, id: MessageId, delta: &str, cx: &mut Context<'_, Self>, ) -> bool

Append a token batch to a streaming message.

pub fn finish(&mut self, id: MessageId, cx: &mut Context<'_, Self>) -> bool

Finish a streaming message and normalize its final Markdown.

pub fn stop(&mut self, id: MessageId, cx: &mut Context<'_, Self>) -> bool

Stop a streaming message, keeping the partial body.

pub fn fail( &mut self, id: MessageId, error: impl Into<String>, cx: &mut Context<'_, Self>, ) -> bool

Mark a message as failed, keeping the partial body.

pub fn set_meta( &mut self, id: MessageId, meta: MessageMeta, cx: &mut Context<'_, Self>, ) -> bool

Replace a message’s footer metadata.

pub fn add_source( &mut self, id: MessageId, source: SourceRef, cx: &mut Context<'_, Self>, ) -> bool

Add one source to a message footer.

pub fn clear(&mut self, cx: &mut Context<'_, Self>)

Remove every message from the transcript.

pub fn remove(&mut self, id: MessageId, cx: &mut Context<'_, Self>) -> bool

Remove one message, e.g. before retrying a failed answer.

Returns whether the message existed.

pub fn replace( &mut self, messages: impl IntoIterator<Item = NewMessage>, cx: &mut Context<'_, Self>, )

Replace the transcript, for loading a session.

pub fn scroll_to_end(&mut self, cx: &mut Context<'_, Self>)

Scroll to the newest message and resume tail following.

pub fn copy_message(&mut self, id: MessageId, cx: &mut Context<'_, Self>)

Copy a message body to the clipboard.

pub fn retry(&mut self, id: MessageId, cx: &mut Context<'_, Self>)

Ask the host to retry a failed message.

pub fn source_clicked(&mut self, source: SourceRef, cx: &mut Context<'_, Self>)

Ask the host to act on a source.
