Cursor is positioned at the end of the text.

pub fn empty() -> Self

Create an empty input state.

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

Insert a character at cursor position.

pub fn insert_str(&mut self, s: &str)

Insert a string at cursor position.

pub fn delete_char_backward(&mut self) -> bool

Delete character before cursor (backspace).

Returns true if a character was deleted.

pub fn delete_char_forward(&mut self) -> bool

Delete character at cursor (delete key).

Returns true if a character was deleted.

pub fn delete_word_backward(&mut self) -> bool

Delete word before cursor.

Returns true if any characters were deleted.

pub fn move_left(&mut self)

Move cursor left by one character.

pub fn move_right(&mut self)

Move cursor right by one character.

pub fn move_home(&mut self)

Move cursor to the start of the text.

pub fn move_end(&mut self)

Move cursor to the end of the text.

pub fn move_word_left(&mut self)

Move cursor left by one word.

pub fn move_word_right(&mut self)

Move cursor right by one word.

pub fn clear(&mut self)

Clear the text and reset cursor.

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

Set the text content.

Cursor is moved to the end.

pub fn text_before_cursor(&self) -> &str

Get text before cursor.

pub fn text_after_cursor(&self) -> &str

Get text after cursor.

pub fn is_empty(&self) -> bool

Check if the input is empty.

pub fn len(&self) -> usize

Get the length of the text in characters.

pub fn text(&self) -> &str
