Implementations

impl VgaChar

pub const fn new(cp: u8, attr: Attribute) -> Self

Construct a VgaChar.

pub fn get_volatile(&self) -> Self

pub fn set_volatile(&mut self, other: Self)

Set a VgaChar and suppress optimization. In case self is on video buffer.

let mut nonnull:NonNull::<VgaChar> = unsafe { NonNull::new_unchecked(VGA_PTR) };
let vchar = nonnull.as_ref().get_volatile();
nonnull.as_mut().get_volatile(vchar & 0xff00);
