pub struct ChatView { /* private fields */ }

Chat message display widget with streaming and tool execution support.

Implementations

impl ChatView

pub fn new() -> ChatView

Create a new ChatView with default settings

pub fn with_config(config: ChatViewConfig) -> ChatView

Create a new ChatView with custom configuration

pub fn config(&self) -> &ChatViewConfig

Get the current configuration

pub fn set_config(&mut self, config: ChatViewConfig)

Set a new configuration

pub fn with_title(self, title: impl Into<String>) -> ChatView

Set the title displayed in the title bar

pub fn with_initial_content( self, render: Box<dyn Fn(&mut Frame<'_>, Rect, &Theme) + Sync + Send>, ) -> ChatView

Set custom initial content renderer (shown when no messages)

Provide a closure for full ratatui control over what to display when the chat has no messages yet.

pub fn with_title_renderer<F>(self, render: F) -> ChatView

where F: Fn(&str, &Theme) -> (Line<'static>, Line<'static>) + Send + Sync + 'static,

Set custom title bar renderer

The function receives the current title and theme, and returns (left_title, right_title) as ratatui Lines.

pub fn set_title(&mut self, title: impl Into<String>)

Set the title displayed in the title bar (mutable setter)

pub fn title(&self) -> &str

Get the current title

pub fn step_spinner(&mut self)

Advance the spinner animation

pub fn add_user_message(&mut self, content: String)

Add a user message (does not force scroll - caller should handle that)

pub fn add_assistant_message(&mut self, content: String)

Add an assistant message (complete)

pub fn add_system_message(&mut self, content: String)

Add a system message (ignores empty messages)

pub fn add_tool_message( &mut self, tool_use_id: &str, display_name: &str, display_title: &str, )

Add a tool execution message

pub fn update_tool_status(&mut self, tool_use_id: &str, status: ToolStatus)

Update a tool message status by tool_use_id - O(1) lookup

pub fn enable_auto_scroll(&mut self)

Re-enable auto-scroll and scroll to bottom (call when user submits a message)

pub fn append_streaming(&mut self, text: &str)

Append text to the streaming buffer

pub fn complete_streaming(&mut self)

Complete the streaming response and add as assistant message

pub fn discard_streaming(&mut self)

Discard the streaming buffer without saving (used on cancel)

pub fn is_streaming(&self) -> bool

Check if currently streaming

pub fn scroll_up(&mut self)

pub fn scroll_down(&mut self)

pub fn render_chat( &mut self, frame: &mut Frame<'_>, area: Rect, pending_status: Option<&str>, )
