Crate dspk_hub 

Verified download and local cache of published artifacts: data files and model weights that dspk crates use but do not ship (licences, size).

• Artifact: what to fetch — id, family, file name, URI (hf://, gh://, zenodo://, https://, file://, see providers), expected SHA-256 and size.
• Hub: Hub::pull downloads into the HubCache and verifies hash and size before the file is committed (an artifact without a hash is refused); Hub::status reads the cache index; Hub::verify re-hashes.
• catalog: which artifacts exist, where they come from and whom to credit, as data only. Each domain is a feature (synapse: electrophysiology artifacts such as Kilosort4’s universal templates); pull fetches a catalog entry by id.

The crate depends on no other dspk crate: the catalogs describe files, the crates that read them (sorters, models) live elsewhere. All network access of the workspace’s libraries is here.

Modules

cache

Local cache of downloaded artifacts (~/.cache/dspk/hub/ or DSPK_HUB_DIR): models/<family>/<slug>/<file> plus an index.json recording each installed file’s hash and size, so status checks never re-read the files (HubCache::verify does).

catalog

Catalogs of published artifacts, as data: what each file is, where it is downloaded from, how it is verified (SHA-256, size) and whom to credit.

download

Model weight downloader with streaming SHA-256 verification and remote link inspection.

providers

URI resolvers converting shorthand provider URIs (hf://, gh://, zenodo://, https://, file://) into direct downloadable URLs.

Structs

Artifact

A published file to fetch and verify.

ArtifactReport

Local state and integrity of one artifact.

Hub

Downloads into and reads from a HubCache.

Functions

pull

Downloads (unless installed) and verifies catalog entry id of Catalog::load_default into the default cache (Hub::from_env_or_default), returning its local path.
