These are all ways that Rust is neutral or better. Were there any ways that Rust was worse? For example, did the previous code use value-type templates? If so how was their absence worked around in the new code?

Chucklefish made some buzz few month ago saying they were writting there new game in Rust, they now stopped and went back to C++.

They're still using Rust for some stuff, just not for the game itself. Wargroove's matchmaking server is still in Rust. That said, yes, this is a good example of what your parent is asking for.

Compile time. For my 9k lines project it takes 20 sec to compile in debug mode and 1 minute in release. Wich is insane because I have to do a lot of runs to test things(where cargo check can't help).

In spite of this i'm in love with Rust

If you modify a single line and rebuild, how much time does it takes, on average ?

I tried to change some constants in random places(in 1 line each time) and on average it's ~10 seconds Also compilation unit in rust is a crate. I guess if your app can be separated in different crates it can ease the pain.

cargo check is 3.11s
