Struct Editor 

pub struct Editor { /* private fields */ }

A single-line text buffer with a cursor. Multi-line editing is not needed for any current form field (transaction notes are one-line memos today) but could grow in-place later.

Implementations

impl Editor

pub fn new(mode: EditMode) -> Self

pub fn with_buffer(mode: EditMode, buffer: impl Into<String>) -> Self

pub fn buffer(&self) -> &str

pub fn cursor(&self) -> usize

pub fn mode(&self) -> EditMode

pub fn vim_mode(&self) -> VimMode

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

pub fn insert_char(&mut self, c: char)

Insert a single character at the cursor. In vim mode, insertion only happens in Insert sub-mode; in emacs mode always.

pub fn delete_backward(&mut self)

pub fn delete_forward(&mut self)

pub fn move_left(&mut self)

pub fn move_right(&mut self)

pub fn move_home(&mut self)

pub fn move_end(&mut self)

pub fn kill_to_end(&mut self)

Delete from the cursor to end-of-line (emacs C-k).

pub fn kill_word_backward(&mut self)

Delete the word before the cursor (emacs C-w).

pub fn enter_insert_mode(&mut self)

pub fn enter_normal_mode(&mut self)

pub fn vim_action(&mut self, action: VimAction)

Execute a vim normal-mode motion or edit by name. Keeping this symbolic rather than key-driven means the event layer can translate key events into these names, and the pure engine is trivial to unit-test.

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 Debug for Editor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
