calculate_hash

Calls <code><a href="/link/digest%3A%3Adigest()?package=mlr3misc&version=0.15.0" data-mini-rdoc="mlr3misc::digest::digest()">digest::digest()</a></code> using the 'xxhash64' algorithm after applying <code>hash_input</code> to each object.
To customize the hashing behaviour, you can overwrite <code>hash_input</code> for specific classes.
For <code>data.table</code> objects, <code>hash_input</code> is applied to all columns, so you can overwrite <code>hash_input</code> for
columns of a specific class.
Objects that don't have a specific method are hashed as is.

Frequently used helper functions and assertions used in
'mlr3' and its companion packages. Comes with helper functions for
functional programming, for printing, to work with 'data.table', as
well as some generally useful 'R6' classes. This package also
supersedes the package 'BBmisc'.
