winit | Window handling library in pure Rust

Can't tell for sure, but (from past experience) this sounds like either a combination of:

Possible cause #1:

• A script failing to properly wrap something like $PWD in double-quotes when accessing it.
• The script being called from a directory with characters in it (such as a space or a quote) that needs to be quoted. Since you are using WSL, I often would suspect that you may have the project on a Windows drive.

OR

Possible cause #2:

• A script failing to properly wrap $PATH in double-quotes when modifying it.
• And, since you have this tagged WSL, the Windows path having characters in the path (like spaces) that always need quoting.
• And, the interop feature of WSL that automatically appends the Windows path to the Linux path at startup so that you can run Windows commands (assuming the .exe is included) such as powershell.exe, Visual Studio Code, and (of course) many others.

In the first case, try building in a different directory, preferably something like ~/src.

In the second case ...

Usually I would recommend finding and fixing the quoting issue as the first step, but:

1. These aren't your scripts
2. You don't need to fix this on a permanent basic, just while you are building.

So in this case, I'd recommend trying the build with the Windows path propagation turned off (temporarily). To do this:

Try this:

So I found a solution if you discover this issue and the code works on other machines. Uninstall rust with rustup self uninstall and then renistall with the standard script curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh and then you should be good.

In order for the mechanism of reading historical data to work, it is necessary to enable the UA_ENABLE_HISTORIZING parameter WHEN BUILDING THE LIBRARY, which is not specified in the official documentation for the library.

You need to setup apache thrift.

add this snippet to your dockerfile.

But when I put the console.log outside the function I get undefined.

That happens because the OBJ asset is loaded asynchronously. That means if you access minObj before the loading process has been finished, runtime errors will occur since the variable is still undefined.

One simple solution is to implement a check before accessing minObj:

I am wondering if the compiler might trim away this kind of exception handling during code optimization, or not?

TL;DR: No, a compiler cannot and must not optimize away such exception handling.

As mentioned in the comments, an empty catch block is not the same as not having try ... catch blocks.

In your example, although there is no code actually executed in the catch block, the exception thrown when a negative number is passed to the fib function is still caught by that block. At that point, the catch block is conceptually entered, then exited pretty swiftly – passing control (silently) to the code immediately following that empty block.

There will also be some (necessary) stack unwinding, and possibly other 'remedial' actions, performed when that catch block is invoked; thus, even such an empty catch block will still actually catch the relevant exceptions (specified as its arguments).

So, for your code (as-is), entering a test value of -3 will result in normal, successful program termination. On my Windows console (invoked from Visual Studio), I see this:

I found another way to do the same thing but without appendChild. I put the canvas directly in the wrap div...
