[][src]Struct pc_keyboard::Keyboard

pub struct Keyboard<T, S> where
    T: KeyboardLayout,
    S: ScancodeSet
{ /* fields omitted */ }

Keyboard<T, S> encapsulates decode/sampling logic, and handles state transitions and key events. Size: 10 bytes

Methods

impl<T, S> Keyboard<T, S> where
    T: KeyboardLayout,
    S: ScancodeSet
[src]

pub fn new(_layout: T, _set: S, handle_ctrl: HandleControl) -> Keyboard<T, S>[src]

Make a new Keyboard object with the given layout.

pub fn set_ctrl_handling(&mut self, new_value: HandleControl)[src]

Change the Ctrl key mapping.

pub fn get_ctrl_handling(&self) -> HandleControl[src]

Get the current Ctrl key mapping.

pub fn clear(&mut self)[src]

Clears the bit register.

Call this when there is a timeout reading data from the keyboard.

pub fn add_word(&mut self, word: u16) -> Result<Option<KeyEvent>, Error>[src]

Processes a 16-bit word from the keyboard.

  • The start bit (0) must be in bit 0.
  • The data octet must be in bits 1..8, with the LSB in bit 1 and the MSB in bit 8.
  • The parity bit must be in bit 9.
  • The stop bit (1) must be in bit 10.

pub fn add_byte(&mut self, byte: u8) -> Result<Option<KeyEvent>, Error>[src]

Processes an 8-bit byte from the keyboard.

We assume the start, stop and parity bits have been processed and verified.

pub fn add_bit(&mut self, bit: bool) -> Result<Option<KeyEvent>, Error>[src]

Shift a bit into the register.

Call this /or/ call add_word - don't call both. Until the last bit is added you get Ok(None) returned.

pub fn process_keyevent(&mut self, ev: KeyEvent) -> Option<DecodedKey>[src]

Processes a KeyEvent returned from add_bit, add_byte or add_word and produces a decoded key.

For example, the KeyEvent for pressing the '5' key on your keyboard gives a DecodedKey of unicode character '5', unless the shift key is held in which case you get the unicode character '%'.
