pub struct KeyboardHotPlugMonitor { /* private fields */ }

Available on crate feature alloc only.

input event notification wrapper

Implementations

impl KeyboardHotPlugMonitor

Warn: Unpredictable! Unsafe! This may cause the program to hang.

pub unsafe fn new(dirty_flag_ptr: NonNull<bool>) -> Result<Self>

enable global keyboard hotplug listener dirty_flag_ptr: recommend static bool pointer

pub unsafe fn notify_mode_loop<Init, Update, Loop, Res>( init: Init, update: Update, tick: Loop, ) -> Result<Res>

where Init: FnMut(usize, &mut ScopedProtocol<Input>) -> Result<Res>, Update: FnMut(usize, &mut ScopedProtocol<Input>) -> Result<Res>, Loop: FnMut(usize, &mut ScopedProtocol<Input>) -> Result<Res>,

support keyboard hotplug (notify + polling flag mode)

param

• init: start register input callback function
• update: update keyboard callback function
• tick: main loop callback function

Usage

fn f(index: usize, input: &mut ScopedProtocol<Input>) -> Result { Ok(()) }
KeyboardHotPlugMonitor::notify_mode_loop(f, f, f)?;

More see examples/test_input_hotplug.rs

pub unsafe fn polling_mode_loop<Init, Update, Loop, Res>( init: Init, update: Update, tick: Loop, ) -> Result<Res>

where Init: FnMut(usize, &mut ScopedProtocol<Input>) -> Result<Res>, Update: FnMut(usize, &mut ScopedProtocol<Input>) -> Result<Res>, Loop: FnMut(usize, &mut ScopedProtocol<Input>) -> Result<Res>,

support keyboard hotplug (pure polling mode)

warn: Poor performance! frequent opening and closing of protocols.

param

• init: start register input callback function
• update: update keyboard callback function
• tick: main loop callback function

Usage

fn f(index: usize, input: &mut ScopedProtocol<Input>) -> Result { Ok(()) }
KeyboardHotPlugMonitor::polling_mode_loop(f, f, f)?;

More see examples/test_polling_hotplug.rs

config

REFRESH_POSITIVE_INPUT_DEVICE_TIME::set configuration can be modified before this KeyboardHotPlugMonitor::polling_mode_loop is used.
