Crate kbd_crossterm 

Crossterm key event conversions for kbd.

This crate converts crossterm’s key events into kbd’s unified types so you can use kbd’s Dispatcher, hotkey parsing, layers, and sequences in a TUI app.

Crossterm reports keys as characters (Char('a')) and modifier bitflags, while kbd uses physical key positions (Key::A) and typed Modifier values.

Extension traits

• CrosstermKeyExt — converts a crossterm::event::KeyCode to a kbd::key::Key.
• CrosstermModifiersExt — converts crossterm::event::KeyModifiers to a Vec<Modifier>.
• CrosstermEventExt — converts a full crossterm::event::KeyEvent to a kbd::hotkey::Hotkey.

Key mapping

Crossterm	kbd	Notes
Char('a') – Char('z')	Key::A – Key::Z	Case-insensitive
Char('0') – Char('9')	Key::DIGIT0 – Key::DIGIT9
Char('-'), Char('='), …	Key::MINUS, Key::EQUAL, …	Physical position
F(1) – F(35)	Key::F1 – Key::F35	F(0) and F(36+) → None
Enter, Esc, Tab, …	Key::ENTER, Key::ESCAPE, Key::TAB, …	Named keys
Media(PlayPause), …	Key::MEDIA_PLAY_PAUSE, …	Media keys
Modifier(LeftControl), …	Key::CONTROL_LEFT, …	Modifier keys as triggers
BackTab, Null, KeypadBegin	None	No kbd equivalent
Non-ASCII Char (e.g., 'é')	None	No physical key mapping

Modifier mapping

Crossterm	kbd
CONTROL	Modifier::Ctrl
SHIFT	Modifier::Shift
ALT	Modifier::Alt
SUPER	Modifier::Super
HYPER, META	(ignored)

Usage

use crossterm::event::{KeyCode, KeyEvent, KeyModifiers};
use kbd::prelude::*;
use kbd_crossterm::{CrosstermEventExt, CrosstermKeyExt, CrosstermModifiersExt};

// Single key conversion
let key = KeyCode::Char('a').to_key();
assert_eq!(key, Some(Key::A));

// Modifier conversion
let mods = KeyModifiers::CONTROL.to_modifiers();
assert_eq!(mods, vec![Modifier::Ctrl]);

// Full event conversion
let event = KeyEvent::new(KeyCode::Char('c'), KeyModifiers::CONTROL);
let hotkey = event.to_hotkey();
assert_eq!(hotkey, Some(Hotkey::new(Key::C).modifier(Modifier::Ctrl)));
