Struct CdiRegistry 

pub struct CdiRegistry { /* private fields */ }

Registry of all discovered CDI specs, indexed by fully-qualified device name.

A fully-qualified CDI device name has the format vendor.com/class=device, e.g. nvidia.com/gpu=0.

Implementations

impl CdiRegistry

pub fn discover() -> Self

Discover and load CDI specs from the standard directories.

Scans /etc/cdi/ and /var/run/cdi/ for *.json and *.yaml files, parses them, and indexes them by kind.

pub fn get_spec(&self, kind: &str) -> Option<&CdiSpec>

Look up a CDI spec by kind (e.g. “nvidia.com/gpu”).

pub fn resolve_device(&self, qualified_name: &str) -> Option<CdiContainerEdits>

Resolve a fully-qualified CDI device name to its container edits.

Format: vendor.com/class=device (e.g. nvidia.com/gpu=0)

Returns the merged container edits (global + device-specific) or None if the device is not found.

pub fn is_empty(&self) -> bool

Check if any CDI specs are available.

pub fn kinds(&self) -> impl Iterator<Item = &str>

Get all available kinds.

pub async fn generate_nvidia_spec() -> Option<CdiSpec>

Generate a CDI spec for NVIDIA GPUs using nvidia-ctk.

Runs nvidia-ctk cdi generate and returns the resulting spec, or None if nvidia-ctk is not available.
