Struct RegistryIndex 

pub struct RegistryIndex {
    pub version: String,
    pub datasets: Vec<DatasetInfo>,
}

Registry index containing all dataset information.

The index is stored as JSON and contains metadata for all datasets in the registry.

Example JSON

{
  "version": "1.0",
  "datasets": [
    {
      "name": "mnist",
      "versions": ["1.0.0", "1.0.1"],
      "latest": "1.0.1",
      "size_bytes": 11490000,
      "num_rows": 70000,
      "schema": { ... },
      "metadata": { ... }
    }
  ]
}

Fields

version: String

Index format version.

datasets: Vec<DatasetInfo>

List of all datasets in the registry.
