Trait Implementations

impl Component for AssistantMessageComponent

fn render(&mut self, width: usize) -> Vec<String>

Render to lines for the given viewport width. Each returned string MUST NOT exceed width in visible width.

fn cache_key(&self, width: usize) -> Option<RenderCacheKey>

Get the cache key for this component’s current state. Return None to disable caching (always re-render).

fn set_hide_thinking(&mut self, hide: bool)

Toggle thinking block visibility. No-op by default. Override for components that display thinking content (AssistantMessageComponent).

fn invalidate(&mut self)

Mark this component as needing re-render. Called when internal state changes (output received, expanded toggled, etc.).

fn render_padded(&mut self, width: usize) -> Vec<String>

Render and pad each line to exactly width visible columns. Default implementation calls render(width) and pads each line with trailing spaces if its visible width is less than width.

fn handle_input(&mut self, _key: &KeyEvent) -> bool

Handle keyboard input. Return true if consumed.

fn handle_paste(&mut self, _text: &str)

Handle a paste event (text from bracketed paste mode). Default no-op; override to process pasted content.

fn is_dirty(&self) -> bool

Check if this component needs re-render. Default: false — the Container’s per-child cache tracking determines whether to re-render. Override to return true for components whose state can change without explicit invalidation (e.g. ToolExecComponent receiving streaming output).

fn clear_dirty(&mut self)

Clear dirty flag after successful render.

fn get_cached_render(&self) -> Option<&RenderCache>

Get cached render output, if available and valid.

fn set_cached_render(&mut self, _cache: RenderCache)

Store render output in cache.

fn is_focusable(&self) -> bool

Whether this component wants focus (for IME cursor positioning).

fn set_expanded(&mut self, _expanded: bool)

Toggle expanded/collapsed state. No-op by default. Override for components that support expand/collapse (tool results, messages, etc.).
