fn assert_default_hashing_controls(ctx: &impl HashStableContext, msg: &str)Expand description
Assert that the provided HashStableContext is configured with the ‘default’
HashingControls. We should always have bailed out before getting to here
with a non-default mode. With this check in place, we can avoid the need
to maintain separate versions of ExpnData hashes for each permutation
of HashingControls settings.
