Generally, no, it doesn’t. The reason of that behavior is that Lombok is an annotation processor for javac but when the kotlin compiler runs it uses javac as well but with no annotation processing so this is why kotlin don’t see declarations that wasn’t yet generated. The only workaround for now is to define strict … Read more
let v2 = vec![1; 10]; println!(“{:?}”, v2); {} is for strings and other values which can be displayed directly to the user. There’s no single way to show a vector to a user. The {:?} formatter can be used to debug it, and it will look like: [1, 1, 1, 1, 1, 1, 1, 1, … Read more
You can print any Object using System.out.println(Object). This overloaded version of println will print out toString representation of your object. If you want to customize what will be printed out, you must override the Object#toString() method, for example: public class A { private String foo; @Override public String toString() { // When you print out … Read more
You will need to override the toString method and return a string representation of what you want. So for example: public class Pair { Object key; Object value; public Pair(Object k, Object v) { key = k; value = v; } public Object getKey() { return key; } public Object getValue() { return value; } … Read more
You can redirect the standard output by calling System.setOut(myPrintStream); Or – if you need to log it at runtime, pipe the output to a file: java MyApplication > log.txt Another trick – if you want to redirect and can’t change the code: Implement a quick wrapper that calls your application and start that one: public … Read more
Starting with Rust 1.47 (2020-10-08), this is no longer true! Almost all traits are now implemented for arrays of arbitrary length. So you can now print arrays of length 33! Old answer below for reference. Sadly, Rust does not support integers as generic parameters yet. Therefore it’s not easy to implement a trait (like Debug) … Read more
Xcode 7.1+ Since Xcode 7.1 beta 2, we can now use quotations within string literals. From the release notes: Expressions interpolated in strings may now contain string literals. For example, “My name is (attributes[“name”]!)” is now a valid expression. (14050788) Xcode <7.1 I don’t think you can do it that way. From the docs The … Read more
This happens because Rust test programs hide the stdout of successful tests in order for the test output to be tidy. You can disable this behavior by passing the –nocapture option to the test binary or to cargo test (but, in this case after — – see below): #[test] fn test() { println!(“Hidden output”) } … Read more
If You have the following piece of code: task task1 { println ‘task1 starting’ } You’re in configuration phase of a task. This phase is run during script evaluation. If You’d like to print something while task is executed You need to add an action for task. It looks like: task task1 << { println … Read more
This is a conceptual question… Imagine You have a big cluster, composed of many workers let’s say n workers and those workers store a partition of an RDD or DataFrame, imagine You start a map task across that data, and inside that map you have a print statement, first of all: Where will that data … Read more
