def dump_hash_public_cache_file
  File.write(opts[:hash_public_cache_file], (opts[:json_serializer] || :to_json.to_proc).call(opts[:hash_public_cache]))
  nil
end

#load_hash_public_cache_file ⇒ Object

Load the hash public cache file, if it exists. This replaces the hash public cache with the values from the file.

  cache.each_value(&:freeze)
  nil
end

#scan_hash_public_cache_dir ⇒ Object

Scan the public directory for files, computing the hash public digest for each. This will not rescan files that already have digest values. If a block is given, it will only calculate the digest for the file if the block returns truthy.
