Struct pc_keyboard::Keyboard [−][src]
pub struct Keyboard<T> where
T: KeyboardLayout, { /* fields omitted */ }
Methods
impl<T> Keyboard<T> where
T: KeyboardLayout,
[src]
impl<T> Keyboard<T> where
T: KeyboardLayout,
pub fn new(_layout: T) -> Keyboard<T>
[src]
pub fn new(_layout: T) -> Keyboard<T>
Make a new Keyboard object with the given layout.
pub fn clear(&mut self)
[src]
pub fn clear(&mut self)
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]
pub fn add_word(&mut self, word: u16) -> Result<Option<KeyEvent>, Error>
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]
pub fn add_byte(&mut self, byte: u8) -> Result<Option<KeyEvent>, Error>
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]
pub fn add_bit(&mut self, bit: bool) -> Result<Option<KeyEvent>, Error>
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]
pub fn process_keyevent(&mut self, ev: KeyEvent) -> Option<DecodedKey>
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 '%'.
