Implementations

impl ControlEvent

pub fn normalized_value(&self) -> Option<f32>

Return the normalised value (0.0–1.0) if applicable.

pub fn id(&self) -> Option<u32>

Return the controller element ID, if any.

Trait Implementations

impl Clone for ControlEvent

fn clone(&self) -> ControlEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ControlEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ControlEvent

fn eq(&self, other: &ControlEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
