Struct GpuCapabilities 

pub struct GpuCapabilities {
    pub has_compute: bool,
    pub has_texture_float: bool,
    pub max_workgroup_size: u32,
    pub max_buffer_size: u64,
}

GPU feature capabilities descriptor.

Use GpuCapabilities::default for native targets and GpuCapabilities::webgpu_conservative when targeting WebGPU / WASM.

Fields

has_compute: bool

True when compute shaders are supported.

has_texture_float: bool

True when texture_float / float32-filterable is available.

max_workgroup_size: u32

Maximum total invocations per workgroup (product of x * y * z sizes).

max_buffer_size: u64

Maximum size of a single buffer in bytes.

Implementations

impl GpuCapabilities

pub fn webgpu_conservative() -> Self

Conservative capabilities for a WebGPU (WASM) context.

Buffer size is limited to 128 MiB as mandated by the WebGPU specification minimum.

pub fn validate_buffer_size(&self, size: u64) -> bool

Returns true when size bytes fit within the maximum buffer limit.

pub fn validate_workgroup(&self, size: u32) -> bool

Returns true when size invocations fit within the workgroup limit.

Trait Implementations

impl Clone for GpuCapabilities

fn clone(&self) -> GpuCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuCapabilities

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

Formats the value using the given formatter.

impl Default for GpuCapabilities

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for GpuCapabilities

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