Struct BackendMask 

pub struct BackendMask(/* private fields */);

Backend kinds allowed to register in this process. A backend outside the mask never runs any code, so a broken GPU driver can be kept out of a worker entirely. CPU is always allowed; TRANSCRIBE_BACKENDS can only narrow the mask.

Implementations

impl BackendMask

pub const CPU: BackendMask

CPU plus host-memory accelerators (BLAS). Always implied.

pub const METAL: BackendMask

Apple Metal.

pub const VULKAN: BackendMask

Vulkan.

pub const CUDA: BackendMask

NVIDIA CUDA.

pub const ROCM: BackendMask

AMD ROCm / HIP.

pub const OTHER: BackendMask

Every backend without a dedicated bit (SYCL, OpenCL, RPC, …).

pub const ALL: BackendMask

Everything. The default.

pub const fn for_backend(backend: Backend) -> BackendMask

The smallest mask that can serve a model-load backend request (Backend::Auto needs everything).

pub const fn bits(self) -> u32

The raw TRANSCRIBE_BACKEND_MASK_* bits.

pub const fn from_bits(bits: u32) -> BackendMask

A mask from raw TRANSCRIBE_BACKEND_MASK_* bits.

pub const fn union(self, other: BackendMask) -> BackendMask

Both masks’ backends.

pub const fn contains(self, other: BackendMask) -> bool

Whether every backend in other is in self.
