VkDrawIndirectCount2InfoKHR

Draw indirect count info

VkDrawIndirectCount2InfoKHR is defined as:

typedef struct VkDrawIndirectCount2InfoKHR {
    VkStructureType sType;
    const void* pNext;
    VkStridedDeviceAddressRangeKHR addressRange;
    VkAddressCommandFlagsKHR addressFlags;
    VkDeviceAddressRangeKHR countAddressRange;
    VkAddressCommandFlagsKHR countAddressFlags;
    uint32_t maxDrawCount;
} VkDrawIndirectCount2InfoKHR;

pub struct DrawIndirectCount2InfoKHR {
    s_type: vk::StructureType,
    p_next: *const c_void,
    address_range: vk::StridedDeviceAddressRangeKHR,
    address_flags: vk::AddressCommandFlagsKHR,
    count_address_range: vk::DeviceAddressRangeKHR,
    count_address_flags: vk::AddressCommandFlagsKHR,
    max_draw_count: u32,
}

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
addressRange is the VkStridedDeviceAddressRangeKHR containing draw parameters.
addressFlags is a VkAddressCommandFlagsKHR value defining the flags for the address range.
countAddressRange is the VkDeviceAddressRangeKHR containing the draw count.
countAddressFlags is a VkAddressCommandFlagsKHR value defining the flags for the count address range.
maxDrawCount specifies the maximum number of draws that will be executed. The actual number of executed draw calls is the minimum of the count specified in countAddressRange and maxDrawCount.
