Hi, Below are answered I give to few people (Richard, etc.) who talk about this topic. > « Irony: Isn't Rust heavily dependent upon Git for its package management? So > if Hg is written in Rust, does that mean that Hg has a dependency on Git? »
Rust is a language, Git is a DVCS. You can use Rust with Fossil if you want ... C is language written for a more robust UNIX : should people stop using it because they are with Windows ?Git was basically written for Linux, should OpenBSD avoid it ? > « Many people do believe that just because an application is written in Rust > rather than in C that it must be "safer". But it is a logical fallacy. » Rust is too recent : you could not tell that, as if it is a rule or a correct theory. There are no evidence for that, and you know that. > « I kind of agree that rewriting fossil in Rust will not buy much » That is my point of view too, but I would like to see people writing a Fossil software with ONLY Rust as a language : I am curious. :-) > « Are you really happy with the idea of Fossil making zero forward progress > for two years, and at the end, you have exactly the same feature set as > before? » Depending on the goal. No ? Three possible goals... a) You want to use Rust to reahc some new developpers, it could be a good idea. b) You would like to improve safety at least to give evidence that Rust does NOT give any advantage. c) You would try an object approach... etc. > « However, the value of Rust is not simply memory management. The > *considerably* more expressive type system, and the much more robust type > checking can reduce LOC while improving both readability and safety. » In theory Rust is far better than C. It has a functional approach which is a good idea, immutability is a good idea, concurrency is in mind, etc. However, I don't see anything that would convince me to use Rust for Fossil. Concurrency improvement could be a good reason, however may I suggest that the Fossil team would wait so some "fallacies" could be seen if it is the case... Best Regards K.
