Struct vulkano::memory::MemoryAllocateInfo

pub struct MemoryAllocateInfo<'d> {
    pub allocation_size: DeviceSize,
    pub memory_type_index: u32,
    pub dedicated_allocation: Option<DedicatedAllocation<'d>>,
    pub export_handle_types: ExternalMemoryHandleTypes,
    pub flags: MemoryAllocateFlags,
    pub _ne: NonExhaustive,
}

Parameters to allocate a new DeviceMemory.

Fields

allocation_size: DeviceSize

The number of bytes to allocate.

The default value is 0, which must be overridden.

memory_type_index: u32

The index of the memory type that should be allocated.

The default value is u32::MAX, which must be overridden.

dedicated_allocation: Option<DedicatedAllocation<'d>>

Allocates memory for a specific buffer or image.

This value is silently ignored (treated as None) if the device API version is less than 1.1 and the khr_dedicated_allocation extension is not enabled on the device.

export_handle_types: ExternalMemoryHandleTypes

The handle types that can be exported from the allocated memory.

flags: MemoryAllocateFlags

Additional flags for the memory allocation.

If not empty, the device API version must be at least 1.1, or the khr_device_group extension must be enabled on the device.

The default value is MemoryAllocateFlags::empty().

_ne: NonExhaustive
