wxRust

Someone had a go at a Rust binding of wxWidgets five years ago: https://github.com/kenz-gelsoft/wxRust As they mention, this is based on a C wrapper round wxWidgets' native C++ API, originally developed to aid in developing a Haskell binding to wxWidgets: http://wxc.sourceforge.net/ The Rust binding is probably bitrotted for modern Rust, but since it's mostly generated, generating a low-level API using bindgen, which is actively maintained, and then a high-level API using a Python script of its own, it might be fairly easy to resurrect. bindgen has got pretty good at converting C++ APIs, so it might be worth trying it on wxWidgets' native API, too. I have no plans to write a GUI application in Rust myself, but i would love for there to be a good option for other people to write native GUI apps in Rust. As many other commenters have noted,

AFAIK, rust-bindgen doesn't currently have support for translating C functions and structs into anything other than the same things in Rust. It's somewhat idiomatic for manually-written bindings, layered on top of the generated ones, to take care of things like providing a memory-safe interface (which can't really be done automatically), converting between native Rust types and C representations if necessary (perhaps including things like Result vs. error codes or nulls), and adding object orientation. If you want to go full automatic, though, you can do a lot with Rust macros, so give them a try. Examples of manual wrappers on top of bindgen - there are many: http://erickt.github.io/blog/2014/12/13/rust-and-mdbm/ https://github.com/kenz-gelsoft/wxRust/blob/rust-servo/src/b... (I don't like the design of this one, actually) https://gith
