Struct BitmapTable 

pub struct BitmapTable<Api: Api = Default, const FREE_ON_DROP: bool = true>(/* private fields */);

Implementations

impl<Api: Api> BitmapTable<Api, true>

pub fn new(count: c_int, width: c_int, height: c_int) -> Result<Self, Error>

where Api: Default,

Allocates and returns a new BitmapTable that can hold count width by height Bitmaps.

Equivalent to sys::ffi::playdate_graphics::newBitmapTable.

pub fn new_with( api: Api, count: c_int, width: c_int, height: c_int, ) -> Result<Self, Error>

Allocates and returns a new BitmapTable that can hold count width by height Bitmaps, using the given api.

Equivalent to sys::ffi::playdate_graphics::newBitmapTable.

pub fn load<P: AsRef<Path>>(path: P) -> Result<Self, ApiError>

where Api: Default,

Allocates and returns a new BitmapTable from the file at path.

If there is no file at path, the function returns error.

Calls sys::ffi::playdate_graphics::loadBitmapTable.

pub fn load_with<P: AsRef<Path>>(api: Api, path: P) -> Result<Self, ApiError>

Allocates and returns a new BitmapTable from the file at path.

If there is no file at path, the function returns error.

Calls sys::ffi::playdate_graphics::loadBitmapTable.

impl<Api: Api, const FOD: bool> BitmapTable<Api, FOD>

pub fn load_into<P: AsRef<Path>>(&mut self, path: P) -> Result<(), ApiError>

Loads the image-table at path into the previously allocated this table.

Equivalent to sys::ffi::playdate_graphics::loadIntoBitmapTable.

pub fn get<'table, BitApi>( &'table self, index: c_int, ) -> Option<Bitmap<BitApi, true>>

where Bitmap<BitApi, true>: 'table, BitApi: Default + BitmapApi,

Returns the index bitmap in this table, if index is out of bounds, the function returns None.

Creates new default api access-point.

Equivalent to sys::ffi::playdate_graphics::getTableBitmap.

pub fn get_with<'table, BitApi: BitmapApi>( &'table self, api: BitApi, index: c_int, ) -> Option<Bitmap<BitApi, true>>

where Bitmap<BitApi, true>: 'table,

Returns the index bitmap in this table, if index is out of bounds, the function returns None.

Produced Bitmap uses passed api access-point.

Equivalent to sys::ffi::playdate_graphics::getTableBitmap.

pub fn info<'table, BitApi: BitmapApi>( &'table self, count: Option<&mut c_int>, width: Option<&mut c_int>, )

Returns the bitmap table’s image count in the count if not None and number of cells across in the width (ditto) if not None .

Equivalent to sys::ffi::playdate_graphics::getTableBitmap.

Trait Implementations

impl<Api: Debug + Api, const FREE_ON_DROP: bool> Debug for BitmapTable<Api, FREE_ON_DROP>

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

Formats the value using the given formatter.

impl<Api: Api, const FOD: bool> Drop for BitmapTable<Api, FOD>

fn drop(&mut self)

Executes the destructor for this type.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
