Struct Editor 

pub struct Editor { /* private fields */ }

A multi-line text editor component.

Defaults to Emacs-style bindings (Ctrl+A, Ctrl+E, Ctrl+K, etc.). Call set_vim_mode_enabled to opt into vim-style modal editing (Normal/Insert mode with hjkl, dd, yy, etc.).

Supports undo/redo, kill-ring (yank/yank-pop), history navigation, word-wise movement, and paste detection for large inserts.

Implementations

impl Editor

pub fn new() -> Self

Create a new empty editor with Emacs-style bindings.

pub fn vim_mode_enabled(&self) -> bool

Returns true if vim modal editing is enabled.

pub fn set_vim_mode_enabled(&mut self, enabled: bool)

Enable or disable vim modal editing.

When enabled the editor starts in Normal mode; press i to insert, Escape to return to Normal. When disabled, Emacs-style bindings are always active.

pub fn mode(&self) -> VimMode

Current vim mode (only meaningful when vim mode is enabled).

pub fn set_mode(&mut self, mode: VimMode)

Switch to the given vim mode.

pub fn text(&self) -> &str

Borrow the current text content.

pub fn cursor_grapheme(&self) -> usize

Current cursor position in grapheme indices.

pub fn set_text(&mut self, text: impl Into<String>)

Replace the entire text buffer and move the cursor to the end.

pub fn push_history(&mut self)

Append the current text to the history ring buffer.

History is capped at max_history items (default 100). The history index is reset so subsequent Up/Down navigation starts from the newest entry.

Trait Implementations

impl Clone for Editor

fn clone(&self) -> Editor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for Editor

fn render(&self, width: u16) -> Result<Rendered, RenderError>

Render this component into lines of text at the given width.

fn handle_input(&mut self, event: &Event) -> InputResult

Handle an input event (key press, resize, mouse, etc.).

fn as_focusable(&self) -> Option<&dyn Focusable>

Cast this component to a Focusable reference, if supported.

fn as_focusable_mut(&mut self) -> Option<&mut dyn Focusable>

Cast this component to a mutable Focusable reference, if supported.

fn render_rect(&self, rect: Rect) -> Result<Rendered, RenderError>

Render this component into a specific rectangular area.

fn wants_key_release(&self) -> bool

Returns true if this component wants to receive KeyEventKind::Release events in addition to Press / Repeat.

impl Default for Editor

fn default() -> Self

Returns the “default value” for a type.

impl Focusable for Editor

fn focused(&self) -> bool

Returns true when this component currently has focus.

fn set_focused(&mut self, focused: bool)

Set or clear the focused state.
