Struct KeyboardReport 

pub struct KeyboardReport {
    pub modifiers: u8,
    pub keycodes: [u8; 6],
}

Keyboard report in the boot protocol layout (8 bytes).

All standard USB keyboards support this layout when placed in boot protocol mode via HidHost::set_protocol with HidProtocolMode::Boot.

Fields

modifiers: u8

Modifier keys bitmask.

Bit 0: Left Ctrl | Bit 1: Left Shift | Bit 2: Left Alt | Bit 3: Left GUI Bit 4: Right Ctrl | Bit 5: Right Shift | Bit 6: Right Alt | Bit 7: Right GUI

keycodes: [u8; 6]

Up to 6 simultaneously pressed key codes (HID usage page 0x07). A value of 0x00 means “no key”; 0x01 means “rollover error”.

Implementations

impl KeyboardReport

pub const DESCRIPTOR: &'static [u8]

Report descriptor for a keyboard sending this report.

It also declares a 1-byte LED output report, which the host sends with SET_REPORT or on the interrupt OUT endpoint. Bit 0: Num Lock | Bit 1: Caps Lock | Bit 2: Scroll Lock | Bit 3: Compose | Bit 4: Kana

pub fn parse(buf: &[u8]) -> Option<Self>

Parse a boot-protocol keyboard report from an 8-byte buffer. Returns None if the buffer is shorter than 8 bytes.

pub const fn to_bytes(&self) -> [u8; 8]

Serialize the report for sending it to the host.

pub fn is_pressed(&self, keycode: u8) -> bool

Returns true if the given HID key code is currently pressed.

pub fn ctrl(&self) -> bool

Returns true if Left Ctrl or Right Ctrl is held.

pub fn shift(&self) -> bool

Returns true if Left Shift or Right Shift is held.

pub fn alt(&self) -> bool

Returns true if Left Alt or Right Alt is held.

pub fn gui(&self) -> bool

Returns true if Left GUI (Win/Cmd) or Right GUI is held.
