Calls digest::digest() to calculate the hash for all objects provided.
The following operations are performed to make hashing more robust:
If an object is a
function(), the formals and the body are hashed separately. This ensures that the bytecode or parent environment are not be included in the hash.If an object is a
data.table::data.table(), the data.table is converted to a regular list. This ensures that keys and indices are not included in the hash.
Note that this only applies to top level objects, these transformations are not done recursively.
