Struct Container 

pub struct Container { /* private fields */ }

Container - a component that contains other components rendered vertically. Supports per-child caching for efficient re-rendering.

Implementations

impl Container

pub fn new() -> Self

pub fn add_child(&mut self, component: Box<dyn Component>)

pub fn remove_child(&mut self, component: &dyn Component)

pub fn clear(&mut self)

pub fn children(&self) -> &[Box<dyn Component>]

pub fn children_mut(&mut self) -> &mut [Box<dyn Component>]

pub fn invalidate_all(&mut self)

Mark all children as needing re-render.

pub fn invalidate_child(&mut self, index: usize)

Mark a specific child as needing re-render by index.

pub fn len(&self) -> usize

Get the number of children.

pub fn is_empty(&self) -> bool

Check if empty.

Trait Implementations

impl Component for Container

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

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

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

Handle keyboard input. Return true if consumed.

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: always re-render (conservative).

fn clear_dirty(&mut self)

Clear dirty flag after successful render.

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 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 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.).

fn set_hide_thinking(&mut self, _hide: bool)

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

impl Default for Container

fn default() -> Self

Returns the “default value” for a type.
