Implementations

impl AutomationEvent

pub fn time(&self) -> Tick

The time of the event used for ordering

pub fn done_time(&self) -> Option<Tick>

pub fn start_time(&self) -> Option<Tick>

pub fn cancel_event(&self) -> Option<bool>

Returns Some if it’s a cancel event the boolean is if it’s CancelAndHold

pub fn run( &self, value: &mut f32, current_tick: Tick, event_start_time: Tick, event_start_value: f32 ) -> bool

Update a parameter based on this event

Returns true if something changed

Trait Implementations

impl Clone for AutomationEvent

fn clone(&self) -> AutomationEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AutomationEvent

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

Formats the value using the given formatter.

impl PartialEq<AutomationEvent> for AutomationEvent

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

This method tests for self and other values to be equal, and is used by ==.

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

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