Struct tui_textarea::Input

pub struct Input {
    pub key: Key,
    pub ctrl: bool,
    pub alt: bool,
}

Backend-agnostic key input type.

When crossterm and/or termion features are enabled, converting their key input types into this Input type is defined.

use tui_textarea::{TextArea, Input, Key};
use crossterm::event::{Event, read};

let event = read().unwrap();

// `Input::from` can convert backend-native event into `Input`
let input = Input::from(event);
// or `Into::into`
let input: Input = event.into();
// Conversion from `KeyEvent` value is also available
if let Event::Key(key) = event {
    let input = Input::from(key);
}

Creating Input instance directly can cause backend-agnostic input as follows.

use tui_textarea::{TextArea, Input, Key};

let mut textarea = TextArea::default();

// Input Ctrl+A
textarea.input(Input {
    key: Key::Char('a'),
    ctrl: true,
    alt: false,
});

Fields

Typed key.

ctrl: bool

Ctrl modifier key. true means Ctrl key was pressed.

alt: bool
