Enum DataRef 

#[non_exhaustive]
pub enum DataRef {
    Local {
        path: String,
    },
    S3 {
        bucket: String,
        key: String,
        region: Option<String>,
    },
    Cached {
        cache_key: CacheKey,
    },
    Stream {
        endpoint: String,
        format: StreamFormat,
    },
    Inline {
        value: Value,

    Zarr {

    },
}

A reference to data that may live in different places. Workers exchange DataRefs instead of raw data.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Local

Data in local filesystem

Fields

path: String

S3

Data in S3-compatible object storage

Fields

bucket: String

key: String

region: Option<String>

Cached

Data in Soma cache (content-addressable)

Fields

cache_key: CacheKey

Stream

Data available as a stream endpoint

Fields

endpoint: String

Inline

Data materialized inline (small values only)

value: Value

Zarr

Data stored as a Zarr v3 array in object storage (chunked tensors).

Fields

bucket: String

array_path: String

Root path of the Zarr array (contains zarr.json + chunk objects).
