Description
Fast, memory constant hashing of R objects
Usage
1
fastdigest(obj, ref_serializer = NULL)
Arguments
obj
The object to generate a hash digest for
ref_serializer
(optional) A serializer for reference-style
objects, see serialize
Details
obj will be hashed using R's internal serialization logic
with a custom target which applies applying Jenkins' SpookyHash (v2) in a
streaming fashion. This avoids (ever) copying the data out of the R object
itself, providing both speed and memory constancy.
It also guarantees that the "representation" of the R object being hashed
is the same as the serialized version would be, if created.
