Struct ToolExecComponent 

pub struct ToolExecComponent { /* private fields */ }

Combined tool execution component — delegates rendering to tool-specific ToolRenderer when available, falls back to a simple name+args+output display.

Background transitions:

• Pending (call only, no result) → toolPendingBg
• Success (call + result, !is_error) → toolSuccessBg
• Error (call + result, is_error) → toolErrorBg

Implementations

impl ToolExecComponent

pub fn new( name: impl Into<String>, renderer: Option<Arc<dyn ToolRenderer>>, args: Value, cwd: String, tool_call_id: String, ) -> Self

pub fn set_started_at(&mut self, instant: Instant)

Set the execution start time (for live duration display).

pub fn set_invalidate_tx(&mut self, tx: UnboundedSender<()>)

Set the invalidation sender for async preview computation.

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

Append text to the output buffer for live streaming (e.g. bang command output). Does NOT mark the tool as complete — subsequent set_result_with_details finalizes.

pub fn set_result_with_details( &mut self, output: impl Into<String>, is_error: bool, details: Option<Value>, )

pub fn set_result(&mut self, output: impl Into<String>, is_error: bool)

pub fn make_invalidation_channel() -> (UnboundedSender<()>, UnboundedReceiver<()>)

Create an invalidation channel pair for async preview computation.

pub fn tick_timer(&mut self) -> bool

Tick the timer: marks dirty every 1s to trigger re-render.

Trait Implementations

impl Component for ToolExecComponent

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.).

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 invalidate(&mut self)

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

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 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 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 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_focusable(&self) -> bool

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

fn set_hide_thinking(&mut self, _hide: bool)

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