Methods

impl Cursor

pub fn new(
    background: Rgb,
    position: Position,
    wrap_around: bool,
    get_direction: Option<fn(key: Key) -> Option<Direction>>
) -> Self

Creates new cursor.

Arguments

background - background color of the cell where cursor is placed. Use termion::color.

position - cursor start position.

wrap_around - should cursor be wrapped around or not.

get_direction - pointer to key handler function (optional). This function should translate key into cursor move direction. Function must return None if key is not handled. If function isn't provided the default function is used.

fn get_direction_default(key: Key) -> Option<Direction> {
    match key {
        Key::Char('a') | Key::Left => Some(Direction::Left),
        Key::Char('s') | Key::Down => Some(Direction::Down),
        Key::Char('w') | Key::Up => Some(Direction::Up),
        Key::Char('d') | Key::Right => Some(Direction::Right),
        _ => None,
    }
}

const START_POSITION: Position = Position(1, 1);
let cursor = Cursor::new(color::Rgb(0, 0, 200), START_POSITION, true, None);
