Atomic inspection of a device’s native manager and Rust callback owner.

Fields

device_ordinal: usize

Process-visible CUDA ordinal inspected by this installation transaction.

status: DeviceMemoryManagerInstallationStatus

Authoritative native installation and callback-health classification.

retry: DeviceMemoryManagerInstallationRetry

Whether a subsequent explicit installation can create, retry, or reuse the manager.

cause: DeviceMemoryManagerInstallationCause

Reason for the recorded disposition or the rejected installation request.

effective_options: Option<DeviceMemoryManagerOptions>

Immutable settings of the existing manager, or None when no manager exists.

identity: Option<DeviceMemoryManagerInstallationIdentity>

Retained callback-owner and partition identity, or None for an unidentified installation.

installation_generation: Option<u64>

Native creation generation, or None when no generation was recorded.

failure_callback_installed: bool

Whether the manager retains a process-lifetime allocation-failure callback.

current_resource_installed: bool

Whether the manager is currently installed as the device-current resource.

failure_callback_panicked: bool

Whether the retained callback has recorded a panic.
