FuzzyItem
is basically a wrapper aroundItem
.Simply put, it is intended to obfuscate whether the value was changed during contract execution.
Currently,
fuzz
is implemented naively as a wrappingu8
, bringing some basic obfuscation while keeping gas usage to a minimum. To improve the obfuscation quality, we can changefuzz
to be either aat the expense of gas usage.
Another limitation is that since we have to keep a reference to
Storage
(to use a dtor), we have to implement both mutable and non-mutable versions e.g.FuzzyItemMut
+FuzzyItem
for it to be supported in bothhandle()
andquery()
.Future PR would be to add an
into_fuzzy_item()
andinto_fuzzy_item_mut()
function toItem
.
