Struct InputEditor 

pub struct InputEditor { /* private fields */ }

Editable input buffer with cursor movement and session history.

History navigation (up/down) is only available while the buffer is untouched — empty, or holding an unedited history recall. The first edit locks navigation until the buffer is submitted or emptied again, so half-typed messages are never clobbered by an arrow key.

Implementations

impl InputEditor

pub fn new() -> Self

pub fn text(&self) -> String

Current buffer contents.

pub fn cursor(&self) -> usize

Cursor position in chars (0 ..= len).

pub fn is_empty(&self) -> bool

pub fn is_edited(&self) -> bool

True while history navigation is locked out by an edit.

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

pub fn backspace(&mut self)

pub fn delete(&mut self)

Delete the char under the cursor (forward delete).

pub fn clear_line(&mut self)

Ctrl-U: clear the whole line.

pub fn left(&mut self)

pub fn right(&mut self)

pub fn home(&mut self)

pub fn end(&mut self)

pub fn word_left(&mut self)

Alt+Left: to the start of the previous word.

pub fn word_right(&mut self)

Alt+Right: past the end of the next word.

pub fn history_up(&mut self)

Up arrow: recall the previous history entry (untouched buffers only).

pub fn history_down(&mut self)

Down arrow: towards newer entries; past the newest clears the buffer.

pub fn submit(&mut self) -> Option<String>

Enter: take the trimmed buffer (recorded in history when non-empty) and reset the editor. None for a blank line.
