Struct VulkanOptions 

pub struct VulkanOptions {
    pub map_unified_device_memory: bool,
}

Backend options a host may set when opening a device. The defaults are what VulkanAccelerator::new and VulkanAccelerator::with_device use.

Fields

map_unified_device_memory: bool

On a device with a single memory heap — an integrated GPU, Apple silicon, a software ICD — there is no second memory for the Device domain to be local to, so its allocations take a host-visible device-local type and write_buffer/read_buffer are a mapped copy rather than a staged copy through a transient buffer and a GPU transfer (ADR 0012). false keeps the discrete-GPU plan (a non-host-visible type, staged transfers) on such devices too; the staging path’s tests use it.

Trait Implementations

impl Clone for VulkanOptions

fn clone(&self) -> VulkanOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for VulkanOptions

impl Debug for VulkanOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VulkanOptions

fn default() -> Self

Returns the “default value” for a type.

impl Eq for VulkanOptions

impl PartialEq for VulkanOptions

fn eq(&self, other: &VulkanOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
