Struct vulkano::memory::ExternalMemoryHandleType

pub struct ExternalMemoryHandleType {
    pub opaque_fd: bool,
    pub opaque_win32: bool,
    pub opaque_win32_kmt: bool,
    pub d3d11_texture: bool,
    pub d3d11_texture_kmt: bool,
    pub d3d12_heap: bool,
    pub d3d12_resource: bool,
    pub dma_buf: bool,
    pub android_hardware_buffer: bool,
    pub host_allocation: bool,
    pub host_mapped_foreign_memory: bool,
}

Describes the handle type used for Vulkan external memory apis. This is not just a suggestion. Check out vkExternalMemoryHandleTypeFlagBits in the Vulkan spec.

If you specify an handle type that doesnt make sense (for example, using a dma-buf handle type on Windows) when using this handle, a panic will happen.

Implementations

impl ExternalMemoryHandleType

pub fn none() -> ExternalMemoryHandleType

Builds a ExternalMemoryHandleType with all values set to false. Useful as a default value.

Example

use vulkano::memory::ExternalMemoryHandleType as ExternalMemoryHandleType;

let _handle_type = ExternalMemoryHandleType {
    opaque_fd: true,
    .. ExternalMemoryHandleType::none()
};

pub fn posix() -> ExternalMemoryHandleType

Builds an ExternalMemoryHandleType for a posix file descriptor.

Example

use vulkano::memory::ExternalMemoryHandleType as ExternalMemoryHandleType;

let _handle_type = ExternalMemoryHandleType::posix();
