Do you mean it is amazing how poor is an experience and how many features, widgets and controls they lack when compared with something like FPC/Lazarus and Qt?

Rust is a nice thing, but its UI ecosystem simply cannot even compare.

Qt and Lazarus had much longer time to grow and mature, and Lazarus can also take a number of pages from the Delphi components book.

What's interesting is the speed at which Rust UI toolkits develop and maybe even mature.

Rust is - by design - antithetical to pretty much every idea of rapid application development paradigm Delphi/VCL and to lesser extent Qt adhere to.

It doesn't matter how many of Rust UI toolkits there are. Consider that there are a lot of Rust game engines, and pretty much zero games written in it, because even C++ gives you better trade-offs in that particular space.

IMO it's not ideal for Rust to have only Rust specific toolkits (at least they need to have other language bindings)

I've tried using Qt (non QML, using rust-qt) last week... initially things were looking fine (despite unsafe everywhere)... but I found quickly that I need unsupported things (deriving from C++ classes), and the project isn't really maintained anymore, so I'll need to so some low level work myself if I want to proceed.
