VkNativeBufferFormatPropertiesOHOS

To obtain format properties of an Open Harmony OS native buffer, include a VkNativeBufferFormatPropertiesOHOS structure in the pNext chain of the VkNativeBufferPropertiesOHOS structure passed to vkGetNativeBufferPropertiesOHOS. The VkNativeBufferFormatPropertiesOHOS structure is defined as:

typedef struct VkNativeBufferFormatPropertiesOHOS {
    VkStructureType sType;
    void* pNext;
    VkFormat format;
    uint64_t externalFormat;
    VkFormatFeatureFlags formatFeatures;
    VkComponentMapping samplerYcbcrConversionComponents;
    VkSamplerYcbcrModelConversion suggestedYcbcrModel;
    VkSamplerYcbcrRange suggestedYcbcrRange;
    VkChromaLocation suggestedXChromaOffset;
    VkChromaLocation suggestedYChromaOffset;
} VkNativeBufferFormatPropertiesOHOS;

pub struct NativeBufferFormatPropertiesOHOS {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    format: vk::Format,
    external_format: u64,
    format_features: vk::FormatFeatureFlags,
    sampler_ycbcr_conversion_components: vk::ComponentMapping,
    suggested_ycbcr_model: vk::SamplerYcbcrModelConversion,
    suggested_ycbcr_range: vk::SamplerYcbcrRange,
    suggested_x_chroma_offset: vk::ChromaLocation,
    suggested_y_chroma_offset: vk::ChromaLocation,
}

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• format is the Vulkan format corresponding to the Open Harmony OS native buffer’s format, or VK_FORMAT_UNDEFINED if there is not an equivalent Vulkan format.
• externalFormat is an implementation-defined external format identifier for use with VkExternalFormatOHOS.
• formatFeatures describes the capabilities of this external format when used with an image bound to memory imported from buffer.
• samplerYcbcrConversionComponents represents a set of VkComponentSwizzle.
• suggestedYcbcrModel represents the color model.
• suggestedYcbcrRange represents the numerical value range.
• suggestedXChromaOffset represents the X chroma offset.
• suggestedYChromaOffset represents the Y chroma offset.
