Struct GpuProbe 

pub struct GpuProbe {
    pub usable_gpu: bool,
    pub force_cpu: bool,
}

What a hardware probe found. The caller fills this (e.g. from a wgpu adapter enumeration, an env override, or a forced-CPU test flag); the policy — turning a probe into a pick — lives in decide so every surface decides identically.

Fields

usable_gpu: bool

A usable GPU adapter was found (a real wgpu device can be created).

force_cpu: bool

The caller forces the CPU path regardless (CI determinism, golden PNGs, FACETT_RENDER_CPU=1, a known-bad driver allowlist hit).

Implementations

impl GpuProbe

pub fn gpu() -> Self

A probe asserting a usable GPU is present.

pub fn cpu_only() -> Self

A probe with no GPU (the fallback path).

pub fn from_env(usable_gpu: bool) -> Self

A probe that reads the FACETT_RENDER_CPU env override on top of a detected-GPU flag. The standard wiring a host uses.

Trait Implementations

impl Clone for GpuProbe

fn clone(&self) -> GpuProbe

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GpuProbe

impl Debug for GpuProbe

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

Formats the value using the given formatter.

impl Default for GpuProbe

fn default() -> GpuProbe

Returns the “default value” for a type.

impl Eq for GpuProbe

impl PartialEq for GpuProbe

fn eq(&self, other: &GpuProbe) -> 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.
