Struct GpuDeviceCapacityProbe 

#[non_exhaustive]
pub struct GpuDeviceCapacityProbe {
    pub cuda_total_bytes: u64,
    pub cuda_free_bytes: u64,
    pub owned_capacity_bytes: u64,
    pub max_declarable_limit_bytes: u64,
    pub max_managed_capacity_bytes: u64,
    /* private fields */
}

Pre-build capacity probe for one CUDA device.

Reports the declarable capacity of one device without acquiring the process owner lease or installing any allocator: the CUDA-visible totals, the NVML physical total when reported, the owned capacity for the requested ownership, and the managed capacity left after the backend reserve. Build-time resolution stays the enforcement authority; this probe predicts ownership-vs-facts inputs without requiring callers to resolve limits through repeated build() failures.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

cuda_total_bytes: u64

CUDA-visible allocation capacity. Ownership and explicit limits are compared against this value. The NVML total plays no part in that comparison.

cuda_free_bytes: u64

CUDA-visible free allocation bytes sampled by the probe; not an admission balance.

owned_capacity_bytes: u64

CUDA-visible total or the promised static-partition limit, in bytes.

max_declarable_limit_bytes: u64

Largest explicit managed-capacity limit this ownership accepts, before the backend reserve is subtracted.

max_managed_capacity_bytes: u64

Owned capacity minus backend reserve, in bytes.
