Struct pc_keyboard::Keyboard
source · pub struct Keyboard<L, S>where
S: ScancodeSet,
L: KeyboardLayout,{ /* private fields */ }Expand description
Encapsulates decode/sampling logic, and handles state transitions and key events.

S: ScancodeSet,

S: ScancodeSet,
sourcepub const fn new(
scancode_set: S,
layout: L,
handle_ctrl: HandleControl,
) -> Keyboard<L, S>
pub const fn new( scancode_set: S, layout: L, handle_ctrl: HandleControl, ) -> Keyboard<L, S>
Make a new Keyboard object with the given layout.
sourcepub fn set_ctrl_handling(&mut self, new_value: HandleControl)
pub fn set_ctrl_handling(&mut self, new_value: HandleControl)
Change the Ctrl key mapping.
sourcepub const fn get_ctrl_handling(&self) -> HandleControl
pub const fn get_ctrl_handling(&self) -> HandleControl
Get the current Ctrl key mapping.
sourcepub fn clear(&mut self)
pub fn clear(&mut self)
Clears the bit register.
Call this when there is a timeout reading data from the keyboard.
sourcepub fn add_word(&mut self, word: u16) -> Result<Option<KeyEvent>, Error>
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.
sourcepub fn add_byte(&mut self, byte: u8) -> Result<Option<KeyEvent>, Error>
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.
sourcepub fn add_bit(&mut self, bit: bool) -> Result<Option<KeyEvent>, Error>
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.
sourcepub fn process_keyevent(&mut self, ev: KeyEvent) -> Option<DecodedKey>
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 ‘%’.
