Struct NcclStatus 

pub struct NcclStatus {
    pub library_path: Option<PathBuf>,
    pub all_found: Vec<PathBuf>,
    pub via_docker: Option<String>,
}

NCCL discovery result. NCCL is loaded dynamically by libtorch, so the probe just hunts for libnccl.so* on the usual library paths — unless Self::via_docker is set, in which case NCCL ships inside the container image and the host scan is skipped.

Fields

library_path: Option<PathBuf>

First libnccl.so* found, if any. Used in the report to show the user which install will be picked up.

all_found: Vec<PathBuf>

All discovered libnccl.so* paths (informational; multiple versions in different prefixes is a misconfiguration source).

via_docker: Option<String>

Docker compose service that owns NCCL on this host. When set, the probe records “via Docker image <svc>” instead of scanning the host filesystem. None means the host runs flodl natively and NCCL must live on it.
