Zarr v2 store generics.

Source: R/zarr_store.R
zarr_store_generics.Rd

Low-level byte-level operations on a ZarrStore. All Zarr v2 I/O goes through these five generics so the storage backend is interchangeable.

Usage

store_get_bytes(store, path, ...)

store_set_bytes(store, path, bytes, ...)

store_delete(store, path, ...)

store_exists(store, path, ...)

store_list(store, prefix, ...)

Arguments

store

A ZarrStore.

path

Character scalar key (slash-separated path string).

...

Not used; present for S7 generic dispatch compatibility.

bytes

Raw vector of bytes to write.

prefix

Character scalar; "" to list all keys.

Value

See individual descriptions above.

Details

  • store_get_bytes(store, path) — return raw vector, or NULL if missing.

  • store_set_bytes(store, path, bytes) — write raw vector; create dirs.

  • store_delete(store, path) — remove key; silent no-op if absent.

  • store_exists(store, path) — logical scalar.

  • store_list(store, prefix) — character vector of keys with given prefix; prefix = "" lists all keys.
