Long Compile Times: Dynamic Linking?

[zyansheep]

I've used the Bevy game engine and I cannot live without the super fast (sometimes <1 second!) dynamic linking support. Is this possible to do with Iced? Being a UI library, Iced applications need lots of design iteration for styling & layout. However, iteration is made tedious with long compile times. Is it possible to implement a feature similar to Bevy's --features bevy/dynamic?

I'm not talking about hot reloading, more just dynamic linking with the lld linker and nightly rust for a significant speedup.

#21 (comment)
Seems to think that dynamic linking won't have much of an effect, but I have observed significant speedups with dynamic linking.

Modifying the main.rs file and recompliling using static linking takes around (6-7) seconds in my small-ish bevy project. While doing the same test using the --features bevy/dynamic reduces it to around (1-3) seconds. (Both using lld and nightly).
I'm going to try and implement this feature in iced to see if I can get similar improvements.

Oh gotcha, ya that isn't currently a feature, but you could create a PR for that feature that would be fantastic!

So, I managed to transfer the feature over from bevy and I got a slight iterative compile time improvement:

// Dynamic Compile Times: 2.49s, 2.53s, 2.40s, 2.76s, 2.26s, 2.45s
// Static Compile Times: 3.03s, 4.22s, 3.50s, 3.20s, 3.06s, 3.70s, 2.85s, 2.87s, 3.68s

Time for my PR!
