Implementations

impl GpuContext

pub fn cpu_fallback() -> Self

Create a CPU-fallback context (always available).

pub fn try_create() -> Result<Self, String>

Attempt to initialize a real wgpu compute device.

pub fn best_available() -> Self

Best available backend: GPU if possible, CPU fallback otherwise.

pub fn activation_report(&self) -> GpuActivationReport

Build an activation report describing the current runtime state.

pub fn is_gpu_available(&self) -> bool

Whether the GPU backend is available.

pub fn run_compute( &self, descriptor: &ComputeDispatchDescriptor, ) -> Result<ComputeDispatchResult, String>

Dispatch an arbitrary WGSL compute kernel.

pub fn validate_shader( &self, label: &str, source: &str, ) -> Result<String, String>

Validate that a WGSL shader compiles successfully on the current device.

pub fn vector_add_f32( &self, lhs: &[f32], rhs: &[f32], ) -> Result<Vec<f32>, String>

Convenience: f32 vector addition for GPU validation.

Trait Implementations

impl Debug for GpuContext

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

Formats the value using the given formatter.
