For pub fn widg(&self) -> T { to work, it would be necessary to make a full clone of the T value. W ith all the bounds in your question, that would look like this:

QUESTION

Why does managing OpenGl in Rust require Unsafe Code?

Asked 2021-Apr-17 at 19:23

I've been writing an app in Rust that uses some OpenGL, and I've observed a trend in how OpenGl is accessed/managed in rust code. Frequently it seems that managing or creating an OpenGl context requires unsafe.

Why do these examples require unsafe code? I haven't been running into any problems because of this unsafe designator, but I'm just curious as to why its there. What kind of problems or constraints do these unsafe requirements impose on developers?

OpenGL is implemented as a library with a C ABI. If you want to call a C function from rust, it always means you have to use unsafe because the C implementation knows nothing about the safety features of rust and naturally doesn't support them. Furthermore, OpenGL uses raw pointers in its API to pass data from or to the GL, which also requires unsafe code in rust.

Determine The Bit Depth of a DynamicImage in Rust

Asked 2021-Mar-31 at 04:27

How could one determine the bit depth of a image::DynamicImage in rust? I'm using fltk-rs function for creating an RgbImageand RgbImage::new() requires that I specify the bit depth of the Rgb byte data its going to be created from. The images I'm loading in my program have various bit depths, so I need to be able to determine the bit depth value for image dynamically.

As @Ivan C said, the easiest way is with a look-up table in a match statement.

QUESTION

Depending on Build Target, use fltk::osxMenuBar or MenuBar in fltk-rs

Asked 2021-Jan-30 at 06:47

I'm creating a cross-platform GUI App with fltk-rs. Depending on which platform I'm targeting (OSX or Windows), I'd like to use a different struct for my menu bar. If I'm targeting OSX, for my menu bar I'd like to use fltk::menu::SysMenuBar and for Windows, I'd like to use fltk::menu::MenuBar.

I don't want to keep to separate versions of my code, one for Windows, and one for OSX, just so I can use different a different Struct for my menu.

What are some approaches to changing which struct is used based on the build target without creating different codebases?

Consulting the Rust Reference on Conditional Compilation. You would use the #[cfg(...)] attribute with the target_os option:

QUESTION

What does it mean to "lock" an app's UI thread?

Asked 2021-Jan-29 at 00:38

I'm using the flkt-rs crate to design a GUI. I was wondering what it means to "lock" the UI thread of my application. Does this mean that no CPU is being allocated to that thread? Why would you want to lock the UI thread? When would then want to unlock it?

Additionally I see that that the fltk::app::lock() function returns a result, which implies that there might be some issues associated with using it. What could prevent you from succesfully locking the UI thread?

lock function from the fltk-rs docs:

ANSWER

Answered 2021-Jan-28 at 21:19

From the FLTK C++ documentation:

In a multithreaded program, drawing of widgets (in the main() thread) happens asynchronously to widgets being updated by worker threads, so no drawing can occur safely whilst a widget is being modified (and no widget should be modified whilst drawing is in progress).

FLTK supports multithreaded applications using a locking mechanism internally. This allows a worker thread to lock the rendering context, preventing any drawing from taking place, whilst it changes the value of its widget.

So you wouldn't lock the UI for long periods of time; just enough time to safely update the state of a widget, and then unlock it again.

What could prevent you from succesfully locking the UI thread?

This may be addressed by the next paragraph in the same documentation:

To incorporate the locking mechanism in the library, FLTK must be compiled with –enable-threads set during the configure process. IDE-based versions of FLTK are automatically compiled with the locking mechanism incorporated if possible. Since version 1.3, the configure script that builds the FLTK library also sets –enable-threads by default.

If the application is compiled to be single-threaded then locking the main thread would lock the entire application permanently. It doesn't explicitly say it, but it seems reasonable that there would be a FailedToLock error in this situation.

This kind of API doesn't feel very "Rusty" and it's likely like this because the fltk-rs crate is a thin wrapper around the C++ library.
