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.
