This is intended to be used within the Cache function, but can be used to evaluate what
a simList would look like once it is converted to a repeatably digestible object.
# S4 method for simList
.robustDigest(object, .objects, length, algo, quick, classOptions)an object to digest.
Character vector of objects to be digested. This is only applicable if there is a list, environment (or similar) with named objects within it. Only this/these objects will be considered for caching, i.e., only use a subset of the list, environment or similar objects. In the case of nested list-type objects, this will only be applied outermost first.
Numeric. If the element passed to Cache is a Path class
object (from e.g., asPath(filename)) or it is a Raster with
file-backing, then this will be
passed to digest::digest, essentially limiting the number of bytes
to digest (for speed). This will only be used if quick = FALSE.
Default is getOption("reproducible.length"), which is set to Inf.
The algorithms to be used; currently available choices are
md5, which is also the default, sha1, crc32,
sha256, sha512, xxhash32, xxhash64,
murmur32, spookyhash and blake3.
Logical or character. If TRUE,
no disk-based information will be assessed, i.e., only
memory content. See Details section about quick in Cache.
Optional list. This will pass into .robustDigest for
specific classes. Should be options that the .robustDigest knows what
to do with.
See robustDigest.
This method strips out stuff from a simList class object that would make it otherwise not
reproducibly digestible between sessions, operating systems, or machines.
This will likely still not allow identical digest results across R versions.
