Enum GpuTestGate

Source

pub enum GpuTestGate {
    Ready(&'static GpuRuntime),
    AbsentDevice,
}

Expand description

The outcome of asking for a device in a test.

Variants§

§

Ready(&'static GpuRuntime)

A runtime resolved; the test body must proceed and assert.

§

AbsentDevice

No device on this host, under a policy that permits running without one. Counted by skipped_for_absent_device and announced on stderr.

Implementations§

Source §

impl GpuTestGate

Source

pub fn runtime(&self) -> Option<&'static GpuRuntime>

The runtime, or None when the host has no device.

Deliberately NOT Option-shaped at the call site by default: a caller that writes let Some(rt) = gate.runtime() else { return } is back to the idiom this module exists to remove. Prefer matching on the gate so the absent arm is written out and visible in review.
