Description

Hello, I'm playing with the basic examples, like a single button changing the window title on click. But every time I run the app after making a change to the title string it takes a little over 10 seconds to recompile (on a 16" i9 MBP).

This is really disappointing coming from both web apps and native apps (Swift/SwiftUI, Delphi/VCL or C++/Qt based). At least when we are talking about basic apps like this.

Any way to improve this? I know the native frameworks I mentioned use dynamic libraries for the framework code while Rust has to recompile from source, but I'm really wondering about solutions rather than reasons for slow compile times.

I'm using the recently released iced 0.2 and Rust 1.48 on macOS 11.1

Research direction
Investigate techniques to reduce Rust compile times for iced applications. Look into incremental compilation settings, alternative linkers like lld or mold, and crate precompilation. Review the iced build pipeline and suggest integrating ccache or sccache. Consider advising users to use stable Rust with optimized build profiles for development.
