An array object that contains rasterization rates.


class MTLRasterizationRateSampleArray : NSObject


The horizontal and vertical properties of a MTLRasterizationRateLayerDescriptor point to MTLRasterizationRateSampleArray objects containing rasterization rates for the layer map. You can use array subscript syntax to access the samples. MTLRasterizationRateSampleArray objects perform bounds checking on any accesses you make to their sample data.
