List keys in local CAS.

For internal use only.

tar_cas_l(cas, keys)

Arguments

cas

File path to the CAS repository. NULL to default to file.path(tar_config_get("store"), "cas") (usually "_targets/cas/").

keys

Character vector of keys in the metadata hashes (tar_meta()$data). Used to restrict the output of the return value to avoid listing all the potentially millions of files in the CAS system.

Value

Character vector of keys (metadata hashes) found in the CAS system.

Details

The short function name helps reduce the size of the tar_repository_cas() format string and save space in the metadata.
