Struct DynamicLines 

pub struct DynamicLines { /* private fields */ }

A component that wraps a Vec<String> buffer that can be updated dynamically. Used for sections whose content changes each frame (pending text, status, etc.).

Implementations

impl DynamicLines

pub fn new() -> Self

pub fn set_lines(&self, new_lines: Vec<String>)

Set the lines for this component.

pub fn clear(&self)

Clear the lines.

pub fn clear_cache(&self)

Clear cached state (for Component::invalidate).

Trait Implementations

impl Component for DynamicLines

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 invalidate(&mut self)

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

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: always re-render (conservative).

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 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 DynamicLines

fn default() -> Self

Returns the “default value” for a type.
