calculate_hash

Calls <code><a href="/link/digest%3A%3Adigest()?package=mlr3misc&version=0.10.0" data-mini-rdoc="mlr3misc::digest::digest()">digest::digest()</a></code> to calculate the hash for all objects provided.
The following operations are performed to make hashing more robust:<ul>
<li>If an object is a <code><a href="/link/function()?package=mlr3misc&version=0.10.0" data-mini-rdoc="mlr3misc::function()">function()</a></code>, the formals and the body are hashed separately.
This ensures that the bytecode or parent environment are not be included
in the hash.</li>
<li>If an object is a <code><a href="https://Rdatatable.gitlab.io/data.table/reference/data.table.html">data.table::data.table()</a></code>, the data.table is converted to a
regular list. This ensures that keys and indices are not included in the hash.</li>
</ul>Note that this only applies to top level objects, these transformations are not done
recursively.

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'.

Arguments

Calls <code><a href='https://rdrr.io/pkg/digest/man/digest.html'>digest::digest()</a></code> to calculate the hash for all objects provided.
The following operations are performed to make hashing more robust:<ul>
<li>If an object is a <code><a href='https://rdrr.io/r/base/function.html'>function()</a></code>, the formals and the body are hashed separately.
This ensures that the bytecode or parent environment are not be included
in the hash.</li>
<li>If an object is a <code><a href='https://Rdatatable.gitlab.io/data.table/reference/data.table.html'>data.table::data.table()</a></code>, the data.table is converted to a
regular list. This ensures that keys and indices are not included in the hash.</li>
