QUESTION
First off, I have no idea how to decently phrase the question, so this is up for suggestions.
Lets say we have following overloaded methods:
...ANSWER
Answered 2022-Mar-17 at 08:29It all makes sense and has a simple pattern besides () -> null being a Callable I think. The Runnable is clearly different from the Supplier/Callable as it has no input and output values. The difference between Callable and Supplier is that with the Callable you have to handle exceptions.
The reason that () -> null is a Callable without an exception is the return type of your definition Callable. It requires you to return the reference to some object. The only possible reference to return for Void is null. This means that the lambda () -> null is exactly what your definition demands. It would also work for your Supplier example if you would remove the Callable definition. However, it uses Callable over Supplier as the Callable has the exact type.
Callable is chosen over Supplier as it is more specific (as a comment already suggested). The Java Docs state that it chooses the most specific type if possible:
Type inference is a Java compiler's ability to look at each method invocation and corresponding declaration to determine the type argument (or arguments) that make the invocation applicable. The inference algorithm determines the types of the arguments and, if available, the type that the result is being assigned, or returned. Finally, the inference algorithm tries to find the most specific type that works with all of the arguments.
QUESTION
I got this below error when run the API-GATEWAY, I tried so many ways but I couldn't solve this issue.
Description:
Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway.
Action:
Please set spring.main.web-application-type=reactive or remove spring-boot-starter-web dependency.
Main Class
...ANSWER
Answered 2021-Aug-01 at 06:17Please note that Spring Cloud Gateway is not compatible with Spring MVC (spring-boot-starter-web). This is outlined in section "How to include Spring Cloud Gateway in the official reference documentation":
Spring Cloud Gateway is built on Spring Boot 2.x, Spring WebFlux, and Project Reactor. As a consequence, many of the familiar synchronous libraries (Spring Data and Spring Security, for example) and patterns you know may not apply when you use Spring Cloud Gateway.
Additionally, it is stated that:
Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. It does not work in a traditional Servlet Container or when built as a WAR.
As already suggested by the error message, you would need to remove the dependency on spring-boot-starter-web. You can list all your direct and transitive dependencies with the following command:

async predicate, the "easy" way
One way would be to join_all!() the Futures that compute the filters on every item. And then filters synchronously based on those:
ANSWER
Answered 2022-Feb-03 at 22:46While you can't return an impl Future from an impl FnMut, you can return a boxed future, i.e. a dyn Future which must be boxed because it's in return position. After a bit of borrow checker tetris, we arrive to this:
QUESTION
I created a simple rest service using java, and springboot. here is my service layer code
...ANSWER
Answered 2022-Jan-11 at 00:24Execution order is: First all initializing expressions are resolved in lexical order (top to bottom through the file), then the constructor runs.
In other words, that userPredicate = line runs before your this.service = service; line. It's doomed to failure, and the compiler knows it, so it will refuse to compile this code.
The fix is trivial - move that userPredicate initialization into the constructor:
QUESTION
The question in the title pretty much says it all. The catch is that T cannot be restricted.
Here is what I have tried:
...ANSWER
Answered 2022-Jan-05 at 18:55If you want the compiler to make calling toMap() an error if T isn't assignable to [K, V] for some K and V, then in some sense it doesn't matter what the output type is in such a case. It could be Map or Map or anything, as long as the toMap() call is a compiler error. I think you'll end up with a runtime error (you can wade through the spec if you really care) so the function won't return... the "actual" return type is never which can be safely widened to Map or anything you want without causing a type safety issue.
Anyway, to make the compiler error happen, you can give toMap() a this parameter which requires this be of ArrayWrapper<[any, any]> or something equivalent. You could use conditional type inference to manually infer K and V from T:
QUESTION
If we have a given predicate p :: [Bool] -> Bool that take an infinite list as parameter and return True or False based on some unknown conditions, and we have no idea what this predicate is.
Can we work out a function f :: ([Bool] -> Bool) -> [Bool] that take such predicate and return an infinite list l where p l == True, assuming that the predicate is satisfiable.
ANSWER
Answered 2021-Dec-08 at 17:24You can think of an infinite list [Bool] as being a binary number with the least significant bit first:

...ANSWER
Answered 2021-Oct-18 at 06:54"Alloy seems designed more for interactive use to explore consistency of models, rather than to find specific solutions for problems."
IMHO, Alloy shines when it comes to validate your own way of thinking. You model something and through the visualization of several instances you can sometime come to realize that what you modeled is not exactly what you'd have hoped for. In that sense, I agree with you.
Yet, Alloy can also be used to find specific solutions to problems. You can overload a model with constraints so that only one instance can be found (i.e. your solution). It works also quite well when your domain space remains relatively small.
Here's your model translated in Alloy :
