about RUST

[primo]

Hi Petr,
i refer to your project in https://github.com/petrSchreiber/Cal...from-ThinBASIC
when you have time only and if possible to add to the test_lib.tbasic and lib.rs how to pass an array of numbers, and an array of strings, and an array of UDT from thinbasic to Rust DLL and to get it back to thinbasic
the reason is that i want to test the rust dll speed in my example http://www.thinbasic.com/community/s...-as-FreeBasic)
and to compare its speed with the freebasic DLL i have used in that example and to the Oxygen module you have used there. of course after increasing the Simpson figure points to thousands so to notice the timings.

the UDTs can be :

Type TBGL_TRGB
    r As Byte
    g As Byte
    b As Byte
  End Type
   
  Type TBGL_TVECTOR3F
    x As Single
    y As Single
    z As Single
  end type

or as you like more suitable
Thanks

Hi Primo,

I think I have it for you I also did a minor cleanup of the whole repository and made it possible to use thinBasic strings without need to convert them to unicode first.

Please have a look here for new ThinBASIC definition:
https://github.com/petrSchreiber/Cal...lib.tbasic#L32

...and calling code:
https://github.com/petrSchreiber/Cal...ib.tbasic#L110

...and here for the Rust code being called:
https://github.com/petrSchreiber/Cal...fined_types.rs

you are so generous Petr to provide such a detailed code, which without i will never be able to send UDT array to Rust.
i have applied the instructions in README.md: cargo build --release, then i have found the rust_interop.dll in the Release folder. and after running the test_lib.tbasic it display the output in magnificent glory:
rust_tb2.PNG
but when i press a key to exit the program, the windows 7/x64 display a pop up: thinbasic has stopped to working ...windows is collecting....
your previous package does not display this message.
amazingly with the same DLL thinbasic does not display the error in windows xp/32
Thank you again, tomorrow i will try to run the Simpson figure generator using the Rust DLL according to the info and code you have provided.

Hi Petr
just now i have found that the msg "thinbasic.exe has stopped working" happened only when we want to exit by pressing a key, but there is no error msg when we close the program from the 'X'
this is in windows 7/x64 with thinbasic V1.10.5.0

Hi Primo,

the root cause was mistake on my side - I passed array of two elements, but told Rust it is 10 element array.
Try now, I am pretty confident it will resolve the issue
