Author here. Panopticon grew out of my frustration about the lack of usable implementations of cutting-edge program analysis research and the fact that the industry standard for RE is a proprietary software that looks like Windows 95. I toyed with the idea of rewriting it in Rust since 1.0 became stable. The whole port took around 3 months. I got the size down from 10.000 to 8.000 loc. Looking back it was the right decision. Programming in Rust is not only more fun, it's definitely easier too. Panopticon used alot sum types that were implemented using boost::variant. Like everything with Boost it kind of worked but was incredible ugly and complex. Replacing them with enums was probably the biggest reason I switched to Rust. Also I found iterator invalidation bugs simply by translating C++ to Rust, thanks Borrow Checker!
