Fields

setVolume: Option<unsafe extern "C" fn(c: *mut SoundSource, lvol: c_float, rvol: c_float)>

void playdate->sound->source->setVolume(SoundSource* c, float lvol, float rvol)

Sets the playback volume (0.0 - 1.0) for left and right channels of the source.

getVolume: Option<unsafe extern "C" fn(c: *mut SoundSource, outl: *mut c_float, outr: *mut c_float)>

void playdate->sound->source->getVolume(SoundSource* c, float* outlvol, float* outrvol)

Gets the playback volume (0.0 - 1.0) for left and right channels of the source.

isPlaying: Option<unsafe extern "C" fn(c: *mut SoundSource) -> c_int>

int playdate->sound->source->isPlaying(SoundSource* c)

Returns 1 if the source is currently playing.

setFinishCallback: Option<unsafe extern "C" fn(c: *mut SoundSource, callback: sndCallbackProc, userdata: *mut c_void)>

Trait Implementations

impl Clone for playdate_sound_source

fn clone(&self) -> playdate_sound_source

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for playdate_sound_source

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

Formats the value using the given formatter.

impl Default for playdate_sound_source

fn default() -> playdate_sound_source

Returns the “default value” for a type.

impl Hash for playdate_sound_source

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_sound_source

fn cmp(&self, other: &playdate_sound_source) -> 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_sound_source

fn eq(&self, other: &playdate_sound_source) -> 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_sound_source

fn partial_cmp(&self, other: &playdate_sound_source) -> 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.

Layout

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.
