Thread: about RUST

  1. #1

    about RUST Programming Language

    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,

    sure thing, I am happy you find it interesting.

    I will work on it today afternoon and will notify you here once ready

    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:
    Click image for larger version. 

Name:	rust_tb2.PNG 
Views:	8 
Size:	12.6 KB 
ID:	9868
    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

    Thank you Petr
    yes it is now works okay like charm

    Hi Petr
    i have found that sin, cos, tan, sqrt, pow and others are not implemented naturally in rust and while searching there are a lot of chaos, there are other people don't know how to to run the math functions.
    if there is something usable from the Rust servers will be great to add to your thinbasic_Rust package
    Thanks

    Hi Primo,

    Rust of course has sin/cos/tan, these are the functions I need and love

    They are functions of given data types, for example f32 (SINGLE) and f64 (DOUBLE).

    Check this snippet:
    let angle_deg: f32 = 45.0; // Equivalent of `dim angle_deg as single = 45`
    let angle_rad = angle_deg.to_radians(); // Easy conversion to radians
    println!("Sinus of {} degrees is {}", angle_deg, angle_rad.sin());
    See here what does Rust offer:
    https://doc.rust-lang.org/std/primitive.f64.html

    This is the link to explore Rust standard library:
    https://doc.rust-lang.org/book/secon...ion/index.html

    ...and this is a very neat and complete book about Rust:
    https://www.rust-lang.org/en-US/

    Primo, what do you think about putting your DLL in Rust to GitHub? I would be happy to contribute, we could learn a lot and share the progress with the thinBasic community.
    Just idea, not mandatory. I enjoy the discussion here a lot

    Hi Petr
    i have tried every imaginable way but not a.sin(). this is working very nice.
    i will read the book step by step at least the introductory parts.
    but this tour with your thinbasic_Rust project was very useful and essential for me, and i think the others will find it like so.
    Thanks
