pub fn init_backends(dir: impl AsRef<Path>) -> Result<()>Expand description
Load backend modules from dir (dynamic builds) and register their
devices. A no-op in static builds. Call once, before the first model load.
Errors with crate::Error::Backend if, after loading, the process has no
registered compute device (a dynamic build pointed at a directory with no
usable modules). This call is idempotent per directory and NOT retryable in
the same process.
This mutates the native process-global device registry. Complete every backend-init call before other threads enumerate devices, query backend availability, or load models; the native registry does not support racing registration against those operations.
