Derives UTF-8-safe text editing independently of a renderer.

Required Methods

fn insert_text(&mut self, insertion: &str)

Inserts text at the active cursor and advances past the insertion.

fn delete_before_cursor(&mut self)

Deletes the Unicode scalar immediately preceding the active cursor.

fn delete_at_cursor(&mut self)

Deletes the Unicode scalar at the active cursor.

fn move_cursor_left(&mut self)

Moves the active cursor one Unicode scalar to the left.

fn move_cursor_right(&mut self)

Moves the active cursor one Unicode scalar to the right.

fn move_cursor_home(&mut self)

Moves the active cursor to the beginning of its logical line.

fn move_cursor_end(&mut self)

Moves the active cursor to the end of its logical line.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
