Implementations

impl CGEventTap<'static>

pub fn new<F: Fn(CGEventTapProxy, CGEventType, &CGEvent) -> CallbackResult + Send + 'static>( tap: CGEventTapLocation, place: CGEventTapPlacement, options: CGEventTapOptions, events_of_interest: Vec<CGEventType>, callback: F, ) -> Result<Self, ()>

impl<'tap_life> CGEventTap<'tap_life>

pub fn with_enabled<R>( tap: CGEventTapLocation, place: CGEventTapPlacement, options: CGEventTapOptions, events_of_interest: Vec<CGEventType>, callback: impl Fn(CGEventTapProxy, CGEventType, &CGEvent) -> CallbackResult + 'tap_life, with_fn: impl FnOnce() -> R, ) -> Result<R, ()>

Configures an event tap with the supplied options and callback, then calls with_fn.

Note that the current thread run loop must run within with_fn for the tap to process events. The tap is destroyed when with_fn returns.

pub unsafe fn new_unchecked( tap: CGEventTapLocation, place: CGEventTapPlacement, options: CGEventTapOptions, events_of_interest: Vec<CGEventType>, callback: impl Fn(CGEventTapProxy, CGEventType, &CGEvent) -> CallbackResult + 'tap_life, ) -> Result<Self, ()>

Caller is responsible for ensuring that this object is dropped before 'tap_life expires. Either state captured by callback must be safe to send across threads, or the tap must only be installed on the current thread’s run loop.

Trait Implementations

impl Drop for CGEventTap<'_>

fn drop(&mut self)
