Crate voxora_backend

Expand description

Cross-cutting hardware backend selection for voxora ASR engines.

Centralises Cpu / Cuda / Metal / Vulkan selection so engines no longer each declare their own cpu / cuda / metal / vulkan feature wiring.

ASR-specific: this crate only models hardware backends that are relevant to the voxora speech-recognition stack. It does not abstract LLama.cpp or any other non-ASR backend.

§Phase 0 surface

Today the crate only exposes:

BackendKind (re-exported from voxora-engine).
Capabilities — compile-time + runtime snapshot.
best_device / best_device_or_error — current “always returns CPU” implementation.

The real candle-backed detection lands in 0.2.x once voxora-backend gains a candle feature flag.

Re-exports§

pub use capabilities::Capabilities;
pub use device::best_device;
pub use device::best_device_or_error;
pub use device::detect;
pub use error::BackendError;

Modules§

capabilities: Snapshot of what backends the current binary supports.
device: Best-effort device selection.
error: Errors returned by voxora-backend.
kind: Hardware backend kind.

Enums§

BackendKind: Compile-time hardware backend the engine was built against.
