Struct CachedContainer 

pub struct CachedContainer { /* private fields */ }

CachedContainer - a Container that caches its rendered output. Used for components that need efficient re-rendering (e.g., chat area).

Implementations

impl CachedContainer

pub fn new() -> Self

pub fn inner(&self) -> &Container

pub fn inner_mut(&mut self) -> &mut Container

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

Add a child component.

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

Remove a child component.

pub fn clear(&mut self)

Clear all children.

pub fn invalidate(&mut self)

Mark as needing re-render.

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

Get children.

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

Get mutable children.

pub fn len(&self) -> usize

Get number of children.

pub fn is_empty(&self) -> bool

Check if empty.

Trait Implementations

impl Component for CachedContainer

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 CachedContainer

fn default() -> Self

Returns the “default value” for a type.
