Features supported by a runtime

Fields

plane: EnumSet<Plane>

Plane features supported by this runtime.

cube_cluster: bool

Clustered launches and intra-cluster operations like cluster shared memory

memory_reinterpret: bool

Enables changing the type of containers during kernel execution.

alignment: bool

Enables explicit alignment. If false, alignment still compiles, but isn’t actually applied.

types: Types

Type support

matmul: MatmulFeatures

Matrix multiplication features

copy_async: bool

Whether copy_async is supported

device_memory_scope: bool

Whether a SyncScope::Device synchronization is a release and an acquire at device scope, so that one cube’s writes to storage are visible to another that synchronizes after it. Without it the same synchronization is a cube barrier and nothing more, which is all WebGPU’s memory model promises, so a kernel whose cubes hand each other data must ask before it runs.

tma: EnumSet<Tma>

Tensor Memory Accelerator supported features

unaligned_io: bool

Whether vectors can be read from / stored to addresses not aligned with the vector_size

Implementations

impl Features

pub fn type_usage(&self, ty: ElemType) -> EnumSet<TypeUsage>

Get the usages for a type

pub fn complex_usage(&self, ty: ElemType) -> EnumSet<ComplexUsage>

Get the complex capability families for a type.

pub fn supports_complex_usage(&self, ty: ElemType, usage: ComplexUsage) -> bool

Whether a complex type supports the requested capability family.

pub fn atomic_type_usage(&self, ty: Type) -> EnumSet<AtomicUsage>

Get the usages for an atomic type

pub fn supports_type(&self, ty: impl Into<Type>) -> bool

Whether the type is supported in any way

pub fn supports_address(&self, ty: impl Into<AddressType>) -> bool

Whether the address type is supported in any way
