Struct Input 

pub struct Input { /* private fields */ }

Single-line text input component.

Supports Emacs-style cursor movement and kill ring operations, bracketed paste, and undo coalescing (pi fish-style).

Implementations

impl Input

pub fn new() -> Self

pub fn with_prompt(self, prompt: impl Into<String>) -> Self

pub fn get_value(&self) -> &str

pub fn set_value(&mut self, value: &str)

pub fn set_on_submit(&mut self, cb: Box<dyn FnMut(String)>)

pub fn set_on_escape(&mut self, cb: Box<dyn FnMut()>)

pub fn set_on_change(&mut self, cb: Box<dyn FnMut(&str)>)

Trait Implementations

impl Component for Input

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 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 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 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 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 Input

fn default() -> Self

Returns the “default value” for a type.

impl Focusable for Input

fn set_focused(&mut self, focused: bool)

fn focused(&self) -> bool
