QUESTION
I am looking for a solution where I might misuse TypeScript's type system.
I have a service which provides a port for a repository (Interface that the Repository must implement) since the service must not know the concrete implementation of the repository. Because of this fact the Interface must also provide a definition of the errors the service can handle.
For this I use ts-results.
I could easily define the errors as strings but I would like to provide some further information from the repository to the service in the case of error. So I tried to define the Errors as Union Type of various Error Classes. The problem is that every default error matches the signature of the more specialized errors.
Thus, in the repository, there is no way to prevent passing any other error to the service (port).
...ANSWER
Answered 2022-Mar-16 at 08:22I think the best solution here is to use discriminated union types. While this looks cumbersome it might be the most secure and explicit way to tell what errors may occur and more specifically what errors can be injected as error into your Result.
See this playglound how the compiler behaves.
QUESTION
I am working on an app which will get info from the user through the buttons and text frames in the MyPanel class. I want to display the courses-infos the user entered in the DisplayTable panel. I want it to update each time the add course button in the MyPanel class is pressed. I tried calling the setLabelText method from the MyPanel class, and what the actual function is supposed to do is update the panel and display the text for each element in the passed lists when the button is clicked, But still could not update. Could you tell me how can I update the DisplayPanel's infoLabel text each time the addCourseButton is pressed?

QUESTION
I am working on an app which will get info from the user through the buttons and text frames in the MyPanel class. So far that part works. Now I want to display the courses-infos the user entered in the DisplayTable panel. I want it to update each time the add course button in the MyPanel class is pressed. I tried adding a function to DisplayTable to add a label each time the button is pressed but I could not get it to work since one is static and one is not. Any ideas on how to do that?(Or any tips on how to improve the app in general :) )

will raise an exception (AssertionError
) if the condition is not met. If an exception is raised, it halts the current control flow and raises until it's caught (or until the program terminates). Typically you use an assert
to indicate something that has gone unexpectedly wrong such that your program should immediately terminate.
What I think you want to do is use a simple if
statement:
QUESTION
I'm trying to use CUDA separable compilation in my project. The project is composed of a binary that depends on a few shared libraries (all built in the same build system). These shared libraries in turn use common CUDA code. When running the binary, I get a segfault similar to here. When I create a minimal example, I get "invalid device function" error instead. If I turn the shared libraries into static libraries, the error goes away. Unfortunately I don't have control over this and need to make it work with shared libraries.
I have seen a couple similar posts here in SO, but they use CMake and the solutions usually involve changing libraries from shared to static, which I can't do in my project. I have double-checked that I'm running the code on the right GPU (and indeed it works if I do some changes, see below), so that's not the issue.
I believe I'm missing something when doing CUDA separable compilation, device linking or creating shared libraries.
Below is a fully reproducible minimal example of the problem:
