Enum GpusSpec 

pub enum GpusSpec {
    All,
    List(Vec<u8>),
}

Parsed --gpus argument value.

Two forms accepted by GpusSpec::parse:

• --gpus all: resolve to all visible CUDA devices via nvidia-smi -L.
• --gpus 0,1,2: explicit comma-separated physical device indices.

Variants

All

Use every visible CUDA device. Resolved against nvidia-smi -L at GpusSpec::resolve time.

List(Vec<u8>)

Explicit list of physical CUDA device indices.

Implementations

impl GpusSpec

pub fn parse(raw: &str) -> Result<Self, String>

Parse a --gpus value. Loud errors on empty, malformed, or duplicate device indices.

pub fn resolve(&self) -> Result<Vec<u8>, String>

Resolve to a concrete list of physical CUDA device indices.

List returns its entries verbatim. All shells out to nvidia-smi -L and counts the result – loud error if nvidia-smi is missing or returns 0 GPUs.
