Implementations

impl EventUnion

pub fn try_as_key(&self) -> Result<&KeyInput, CheckedCastError>

Attempt to access self as key.

Will succeed if the cast is safe, even if key was not the logically inhabited formof self, i.e. does not check that self was last written as key as longas the underlying memory is safe (not necessarily logical) to interpret as key.

pub fn as_key(&self) -> &KeyInput

Access self as key. Same conditions as [try_as_key]but panics on failure.

pub fn try_as_mouse(&self) -> Result<&MouseInput, CheckedCastError>

Attempt to access self as mouse.

Will succeed if the cast is safe, even if mouse was not the logically inhabited formof self, i.e. does not check that self was last written as mouse as longas the underlying memory is safe (not necessarily logical) to interpret as mouse.

pub fn as_mouse(&self) -> &MouseInput

Access self as mouse. Same conditions as [try_as_mouse]but panics on failure.

pub fn try_as_touch(&self) -> Result<&TouchInput, CheckedCastError>

Attempt to access self as touch.

Will succeed if the cast is safe, even if touch was not the logically inhabited formof self, i.e. does not check that self was last written as touch as longas the underlying memory is safe (not necessarily logical) to interpret as touch.

pub fn as_touch(&self) -> &TouchInput

Access self as touch. Same conditions as [try_as_touch]but panics on failure.

pub fn try_as_axis(&self) -> Result<&AxisInput, CheckedCastError>

Attempt to access self as axis.

Will succeed if the cast is safe, even if axis was not the logically inhabited formof self, i.e. does not check that self was last written as axis as longas the underlying memory is safe (not necessarily logical) to interpret as axis.

pub fn as_axis(&self) -> &AxisInput

Access self as axis. Same conditions as [try_as_axis]but panics on failure.

pub fn try_as_gamepad_button( &self, ) -> Result<&GamepadButtonInput, CheckedCastError>

Attempt to access self as gamepad_button.

Will succeed if the cast is safe, even if gamepad_button was not the logically inhabited formof self, i.e. does not check that self was last written as gamepad_button as longas the underlying memory is safe (not necessarily logical) to interpret as gamepad_button.

pub fn as_gamepad_button(&self) -> &GamepadButtonInput

Access self as gamepad_button. Same conditions as [try_as_gamepad_button]but panics on failure.

pub fn try_as_raw_midi(&self) -> Result<&RawMidiInput, CheckedCastError>

Attempt to access self as raw_midi.

Will succeed if the cast is safe, even if raw_midi was not the logically inhabited formof self, i.e. does not check that self was last written as raw_midi as longas the underlying memory is safe (not necessarily logical) to interpret as raw_midi.

pub fn as_raw_midi(&self) -> &RawMidiInput

Access self as raw_midi. Same conditions as [try_as_raw_midi]but panics on failure.
