Arrays are a powerful and efficient data structure in Rust that provide a fixed-size collection of elements. I think this will equally efficient as Paul R's solution. I think I may be able to use TrueForAll (T) but I'm not sure. The really difference between TrueForAll, and my LINQ code is: LINQ code uses the fluent (or maybe also query) syntax, where TrueForAll is just a normal function where you send the array as a parameter.

The following example tests whether all elements in the array are bigger than 10. // Otherwise the elements are not equal. When I did, it dropped down to 6.4e-10 ns per element, which I find unbelievable. @MohammedNoureldin - well if it's encountered an element that doesn't satisfy the condition, it's safe to say that not, You don't need to go through the entire array, you can just exit if you find anything that isn't a zero, Building a safer community: Announcing our new Code of Conduct, Balancing a PhD program with a startup career (Ep. Why wouldn't a plane start its take-off run from the very beginning of the runway to keep the option to utilize the full runway if necessary? Namespaces and Operator Overloading in C++, clang-format stack all if-statement arguments if they are too long. So, we can directly pass our integer array to numpy.any() which expects a bool array. Here's an example: We can also initialize the array with specific values using the following syntax: Array elements in Rust can be accessed using their index, which starts from 0. Slicing is done using the range operator (..). Consider the following example. Method 2 (Compare with first): The idea is simple. Order is order, but the coefficient matters a great deal too. It's still broken - hint: one of the return statements is in the wrong place.

Logic is same i.e. The every() method is an iterative method. 1 I create the following array like this: array<UInt16>^ temp = gcnew array<UInt16> (1000); How do I determine if this entire array has been filled with zero or not. As all elements were 0 in the array arr, therefore the returned bool array had only True values. Just like the previous solution, we can use List Comprehension to iterate over each element in the numpy array and create a list of values which are non zero. I think the following is more readable than the highest rated answer and I would wager more efficient too (but havent benchmarked). Check the result every few hundred iterations for early exit.
