I don’t know the exact page unfortunately since I am reading it in an epub.
I am having trouble understanding what this code does and why it is needed:
fn dead(&mut self, ctx: &mut BTerm) {
...
if let Some(key) = ctx.key {
match key {
VirtualKeyCode::P => self.restart(),
VirtualKeyCode::Q => ctx.quitting = true,
_ => {}
}
}
}
What exactly does the Some(key) bit do? Is it destructuring the Option<bracket_lib::prelude::VirtualKeyCode> object?
Just switching on ctx.key obviously doesn’t work, but I don’t quite get why.
