hash_xxhash() returns a character vector of hexadecimal
xxHash hashes.
hash_raw_xxhash() returns a character scalar.
hash_obj_xxhash() returns a character scalar.
hash_file_xxhash() returns a character vector of xxHash
hashes.
Character vector. If not a character vector, then
as.character() is used to try to coerce it into one. NA entries
will have an NA hash.
Workspace format version to use, see
base::serialize().
Character vector of file names.
hash_raw_xxhash() calculates the xxHash hash of the bytes
of a raw vector.
hash_obj_xxhash() calculates the xxHash hash of an R
object. The object is serialized into a binary vector first.
hash_file_xxhash() calculates the xxHash hash of one or
more files.
The 64 functions caculate the 64 bit variant
of xxHash. Otherwise they work the same.
Other hash functions:
hash_animal(),
hash_emoji(),
hash_md5(),
hash_sha1(),
hash_sha256()
hash_xxhash(c("foo", NA, "bar", ""))
