I get an error in the test that I added, though:

Caused by:
  process didn't exit successfully: `C:\Users\UMRH\repos\clipboard-win\target\debug\deps\test_clip-66edde24978329a6.exe should_work_with_filelist --exact --nocapture` (exit code: 0xc0000005, STATUS_ACCESS_VIOLATION)

Occasionally, I will get

(exit code: 0xc0000374, STATUS_HEAP_CORRUPTION)

instead of

(exit code: 0xc0000005, STATUS_ACCESS_VIOLATION)

so I suspect I am doing memory management wrong somehow. If anyone has any pointers (pun) on how to figure that part out, I would greatly appreciate it!

I had to disable no_std because I couldn't figure out how to get the code to run otherwise. Apologies for my rookie Rust skills.

Background: I am writing a file manager app in the tauri framework (https://tauri.app/) to learn rust. I come from a python background.

The funny thing is that the code above works for the first copy action in the sense that I am actually able to paste the file in Explorer. If I try to copy another file afterwards my Tauri app crashes with no stack trace

I left some comments which potentially might fix issue
I'll give it a better look tomorrow

[DoumanAsh]

@mchels I applied comments myself, please check

[DoumanAsh]

Noticed there is some issue, let me try to see if I can write test for this code

[DoumanAsh]

@mchels I fixed memory corruption in my code, so now it should correctly set file from string.

Let me know how it looks to you.
I think for what you want it is better to have API that accepts list of strings, rather than single string

Absolutely agree. The code I pushed was just what I was able to do myself.
I will take a look at the rest tomorrow. Thank you for looking into this!

@DoumanAsh I have pushed a commit that sets a list of strings rather than a single string. It seems to work for me.

I released version 4.5.0
