I think you missed Davide's comment below. Actually the binary became quite small when I used cargo build --release to build it. So, my comment above is not accurate any more.
You are right. Without including debugging feature, by adding --release option, the size would decrease much smaller.
But, when I build and compared two simple button apps, I got the result :
Rust app is 17Mb
C++ app is only 132Kb.
I also tried a small GUI app using C++ that had a feature of simple datagrid (table) where the cells are editable and found the file size was about 1Mb which is acceptable. This type of desktop GUI app is one that I had developed in the past using Visual Basic 6.
One thing that I also found when compiling even a small Rust app like that, the compile time was very long on my computer. It could take 1 hour or more.
