Struct Cache 

pub struct Cache(/* private fields */);

Cached sound source api end-point.

Stores one reference, so size on stack is eq usize.

All calls approximately costs ~1 deref.

Trait Implementations

impl Api for Cache

fn set_volume( &self, ) -> unsafe extern "C" fn(c: *mut SoundSource, lvol: c_float, rvol: c_float)

Returns sys::ffi::playdate_sound_source::setVolume

fn get_volume( &self, ) -> unsafe extern "C" fn(c: *mut SoundSource, outl: *mut c_float, outr: *mut c_float)

Returns sys::ffi::playdate_sound_source::getVolume

fn is_playing(&self) -> unsafe extern "C" fn(c: *mut SoundSource) -> c_int

Returns sys::ffi::playdate_sound_source::isPlaying

fn set_finish_callback( &self, ) -> unsafe extern "C" fn(c: *mut SoundSource, callback: sndCallbackProc, userdata: *mut c_void)

Returns sys::ffi::playdate_sound_source::setFinishCallback

impl Clone for Cache

fn clone(&self) -> Cache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cache

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

Formats the value using the given formatter.

impl Default for Cache

fn default() -> Self

Returns the “default value” for a type.

impl From<&NonNull<playdate_sound_source>> for Cache

fn from(ptr: &NonNull<playdate_sound_source>) -> Self

Converts to this type from the input type.

impl From<&'static playdate_sound_source> for Cache

fn from(r: &'static playdate_sound_source) -> Self

Converts to this type from the input type.

impl From<*const playdate_sound_source> for Cache

fn from(ptr: *const playdate_sound_source) -> Self

Converts to this type from the input type.

impl From<NonNull<playdate_sound_source>> for Cache

fn from(ptr: NonNull<playdate_sound_source>) -> Self

Converts to this type from the input type.

impl Copy for Cache

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.
