Implementations

impl Keyboard

pub fn down(&self, scan: u8) -> bool

Is the key with this scancode held?

pub fn table(&self) -> &[bool; 128]

The whole held-key table, like the array a custom keyboard ISR fills.

pub fn hit(&self) -> bool

Is there a key in the BIOS buffer? (INT 16h, AH=01h, kbhit().)

pub fn read(&mut self) -> Option<KeyPress>

Take the next key from the BIOS buffer (INT 16h, AH=00h, getch()), without waiting.

pub fn flush(&mut self)

Drop all buffered keys (what games did before “press any key”).

pub fn port60(&self) -> u8

Last code on port 0x60: the scancode, with bit 7 set for a release.

pub fn press(&mut self, scan: u8, ascii: u8)

Feed a key press (host side). ascii is 0 for keys without a character.

pub fn release(&mut self, scan: u8)

Feed a key release (host side).

pub fn shift(&self) -> bool

pub fn ascii_for(scan: u8, shift: bool) -> u8

The ASCII code of a scancode on a US keyboard.
