Fields

flags: CapabilityFlags

The boolean capabilities.

min_uniform_buffer_offset_alignment: u32

Required byte alignment for a uniform-buffer binding offset.

max_storage_buffer_bytes: u64

Largest single storage buffer binding, bytes.

max_storage_buffers_per_shader_stage: u32

Maximum storage-buffer bindings visible to one shader stage.

max_texture_dim: u32

Largest 2-D texture dimension, texels.

max_texture_dim_3d: u32

Largest 3-D texture dimension, texels.

r32float: TextureFormatCapabilities

r32float sampling and storage-write support.

rg32float: TextureFormatCapabilities

rg32float sampling and storage-write support.

rgba32float: TextureFormatCapabilities

rgba32float sampling and storage-write support.

Implementations

impl Capabilities

pub fn hardware_ray_tracing(&self) -> bool

Hardware acceleration-structure traversal is available.

This is a resource capability, not evidence that a renderer has wired a complete hardware quality path.

pub fn ray_query(&self) -> bool

Hardware acceleration structures and WGSL ray queries are available.

pub fn mesh_shaders(&self) -> bool

Mesh shading is available.

pub fn bindless(&self) -> bool

Bindless descriptor arrays are available.

pub fn timestamp_queries(&self) -> bool

GPU timestamp queries are available.

pub fn subgroup_ops(&self) -> bool

Subgroup operations are available.

pub fn depth_read_while_sampled(&self) -> bool

One pass may depth-test against a texture it also samples.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Capabilities

impl Debug for Capabilities

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

Formats the value using the given formatter.

impl Default for Capabilities

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Capabilities

impl PartialEq for Capabilities

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

Equality operator ==.

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

Inequality operator !=.
