Struct DeviceCapabilities 

pub struct DeviceCapabilities {
    pub ray_tracing: bool,
    pub selectable_upscaler: bool,
    pub reuses_build_slots: bool,
    pub rewrites_draws: bool,
}

GPU/device capability flags, queried from the backend once it is built. Surfaced so the settings menu can gray out (and make inert) toggles the device cannot honor – e.g. ray-traced reflections on a GPU without hardware ray tracing. Mirrors an RHI-style capability set: a handful of bools held in memory and re-queried each launch, never persisted, so it is always correct for the current device + driver.

Fields

ray_tracing: bool

Hardware ray tracing for the RT-reflections pass: DXR 1.1 on DirectX, the ray-query device extensions on Vulkan (and not under XeSS), and MTLDevice::supportsRaytracing on Metal.

selectable_upscaler: bool

Whether the upscaler implementation is a choice (FSR3 / DLSS / XeSS) rather than fixed. DirectX and Vulkan offer the selection; Metal always upscales through MetalFX, so the row has nothing to pick.

reuses_build_slots: bool

Whether a retired build-time draw slot may be recycled by a runtime clone. Metal’s per-frame RT topology refresh re-admits recycled build-time slots; DirectX / Vulkan key their cull BVH + RT tables to fixed build-time indices and cannot refit, so only the runtime-append region recycles there. Read by the engine’s draw-slot allocator.

rewrites_draws: bool

Whether a built draw slot’s material and cull distance may be rewritten in place (RenderBackend::set_draw_material / RenderBackend::set_draw_cull_distance). Metal rebuilds its per-object buffer from the draw list every frame, so a rewritten slot draws with the new material next frame; DirectX / Vulkan bake per-object material state at build time and would keep drawing the old one. Read by the editor’s live draw seam, which sends the edit to a world rebuild instead.

Implementations

impl DeviceCapabilities

pub const ALL: Self

Every capability present. The trait default, so a backend that does not report capabilities never wrongly disables a toggle (it keeps the prior behavior: the feature no-ops with a warning on an incapable device).

Trait Implementations

impl Clone for DeviceCapabilities

fn clone(&self) -> DeviceCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DeviceCapabilities

impl Debug for DeviceCapabilities

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

Formats the value using the given formatter.

impl Default for DeviceCapabilities

fn default() -> Self

Returns the “default value” for a type.
