Fields

newSignal: Option<unsafe extern "C" fn() -> *mut ControlSignal>

ControlSignal* playdate->sound->controlsignal->newSignal(void)

Creates a new control signal object.

freeSignal: Option<unsafe extern "C" fn(signal: *mut ControlSignal)>

void playdate->sound->controlsignal->freeSignal(ControlSignal* signal)

Frees the given signal.

clearEvents: Option<unsafe extern "C" fn(control: *mut ControlSignal)>

void playdate->sound->controlsignal->clearEvents(ControlSignal* signal)

Clears all events from the given signal.

addEvent: Option<unsafe extern "C" fn(control: *mut ControlSignal, step: c_int, value: c_float, interpolate: c_int)>

void playdate->sound->controlsignal->addEvent(ControlSignal* signal, int step, float value, int interpolate)

Adds a value to the signal’s timeline at the given step. If interpolate is set, the value is interpolated between the previous step+value and this one.

removeEvent: Option<unsafe extern "C" fn(control: *mut ControlSignal, step: c_int)>

void playdate->sound->controlsignal->removeEvent(ControlSignal* signal, int step)

Removes the control event at the given step.

getMIDIControllerNumber: Option<unsafe extern "C" fn(control: *mut ControlSignal) -> c_int>

int playdate->sound->controlsignal->getMIDIControllerNumber(ControlSignal* signal)

Returns the MIDI controller number for this ControlSignal, if it was created from a MIDI file via playdate→sound→sequence→loadMIDIFile().

Trait Implementations

impl Clone for playdate_control_signal

fn clone(&self) -> playdate_control_signal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for playdate_control_signal

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

Formats the value using the given formatter.

impl Default for playdate_control_signal

fn default() -> playdate_control_signal

Returns the “default value” for a type.

impl Hash for playdate_control_signal

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl Ord for playdate_control_signal

fn cmp(&self, other: &playdate_control_signal) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for playdate_control_signal

fn eq(&self, other: &playdate_control_signal) -> 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.

impl PartialOrd for playdate_control_signal

fn partial_cmp(&self, other: &playdate_control_signal) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
