class RFastdigest(RPackage):
"""Fast, Low Memory-Footprint Digests of R Objects
Provides an R interface to Bob Jenkin's streaming, non-cryptographic
'SpookyHash' hash algorithm for use in digest-based comparisons of R
objects. 'fastdigest' plugs directly into R's internal serialization
machinery, allowing digests of all R objects the serialize() function
supports, including reference-style objects via custom hooks. Speed is
high and scales linearly by object size;
memory usage is constant and negligible."""
