Fields

loadVideo: Option<unsafe extern "C" fn(path: *const c_char) -> *mut LCDVideoPlayer>

LCDVideoPlayer playdate->graphics->video->loadVideo(const char* path)

Opens the pdv file at path and returns a new video player object for rendering its frames.

freePlayer: Option<unsafe extern "C" fn(p: *mut LCDVideoPlayer)>

void playdate->graphics->video->freePlayer(LCDVideoPlayer* p)

Frees the given video player.

setContext: Option<unsafe extern "C" fn(p: *mut LCDVideoPlayer, context: *mut LCDBitmap) -> c_int>

int playdate->graphics->video->setContext(LCDVideoPlayer* p, LCDBitmap* context)

Sets the rendering destination for the video player to the given bitmap. If the function fails, it returns 0 and sets an error message that can be read via getError().

useScreenContext: Option<unsafe extern "C" fn(p: *mut LCDVideoPlayer)>

void playdate->graphics->video->useScreenContext(LCDVideoPlayer* p)

Sets the rendering destination for the video player to the screen.

renderFrame: Option<unsafe extern "C" fn(p: *mut LCDVideoPlayer, n: c_int) -> c_int>

void playdate->graphics->video->renderFrame(LCDVideoPlayer* p, int n)

Renders frame number n into the current context. In case of error, the function returns 0 and sets an error message that can be read via getError().

getError: Option<unsafe extern "C" fn(p: *mut LCDVideoPlayer) -> *const c_char>

const char* playdate->graphics->video->getError(LCDVideoPlayer* p)

Returns text describing the most recent error.

getInfo: Option<unsafe extern "C" fn(p: *mut LCDVideoPlayer, outWidth: *mut c_int, outHeight: *mut c_int, outFrameRate: *mut c_float, outFrameCount: *mut c_int, outCurrentFrame: *mut c_int)>

void playdate->graphics->video->getInfo(LCDVideoPlayer* p, int* outWidth, int* outHeight, float* outFrameRate, int* outFrameCount, int* outCurrentFrame)

Retrieves information about the video, by passing in (possibly NULL) value pointers.

getContext: Option<unsafe extern "C" fn(p: *mut LCDVideoPlayer) -> *mut LCDBitmap>

LCBitmap* playdate->graphics->video->getContext(LCDVideoPlayer* p)

Gets the rendering destination for the video player. If no rendering context has been setallocates a context bitmap with the same dimensions as the vieo will be allocated.

Trait Implementations

impl Clone for playdate_video

fn clone(&self) -> playdate_video

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for playdate_video

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

Formats the value using the given formatter.

impl Default for playdate_video

fn default() -> playdate_video

Returns the “default value” for a type.

impl Hash for playdate_video

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_video

fn cmp(&self, other: &playdate_video) -> 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,

Restrict a value to a certain interval.

impl PartialEq for playdate_video

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

impl PartialOrd for playdate_video

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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.
