Enum StreamPriority 

pub enum StreamPriority {
    Default,
    Low,
    High,
}

Stream priority hint, mapped to the backend’s native priority range.

CUDA convention is that lower numerical priorities run first; this enum is the portable abstraction so other runtimes can adopt it without changing their public surface. Backends clamp to their supported range — passing StreamPriority::Low on a device whose only priority bucket is the default is harmless.

The motivating use case is sharing a single GPU with a desktop compositor (WSL2, dev laptops, single-GPU workstations): running long compute batches on a low-priority stream lets the compositor preempt cleanly and keeps the UI responsive.

Variants

Default

Default backend priority — current behavior on every backend.

Low

Lowest priority the backend supports. Useful when sharing the GPU with an interactive workload such as a compositor; long-running compute batches yield to higher-priority work like UI rendering.

High

Highest priority the backend supports. Useful for latency-critical foreground work that must not be preempted by background batches.
