I haven't come across such a ConcurrentCounter library, but crates.io is huge, maybe you find something. However, if you are mostly concerned with primitives such as i32, there is a better alternative call: Atomics, definitely worth checking out.

Nevertheless, your approach of generalizing the ConcurrentCounter is going in a good direction. In the context of operation overloading, std::ops is worth a look. Specifically, you need Add, Sub, and Mul, respectively. Also, you need a Copy bound (alternatively, a Clone would also do). So you were pretty close:

The problem is that you are not aligning the text within the individual Views. Your example mistakenly aligns the inner View elements within the larger View element rather than aligning the text.

To center-align the text vertically within their Views you just need to add justifyContent: "center" to those individual three green Views.

Here's an example: https://codesandbox.io/s/recursing-kirch-n8one?file=/src/App.js:393-417

To further explain why you were experiencing the issue you did, see this screenshot with boxes outlining the space the elements were taking up on-screen:

You can see the inner Views are only taking up the needed width of the text elements inside, but are using the max height available to them.

Because you can't have braces in that context. If you look at cppreference on list initialization, you see that the case inside a ternary operator isn't defined. So it can't be parsed correctly and you get the error you have.

You'd have to use something like this :

The 3rd parameter of bindParam must be integer not a date

You are not measuring the elapsed time correctly:

1. total_send_time measures the duration of the spawn() call, but as the actual task is executed asynchronously, start_in.elapsed() does not give you any information about how much time the task actually takes.

2. The ran in time, as measured by start.elapsed() is also not useful at all. As you are using blocking sleep operation, you are just measuring how much time your app has spent in the std::thread::sleep()

3. Last but not least, your time_to_sleep calculation is completely incorrect, because of the issue mentioned in point 1.

See microsoft/TypeScript#43667 for a canonical answer. This is a design limitation of TypeScript.

As you might be aware: in TypeScript's structural type system, Child is a subtype of Base even though it is not explicitly declared as such. So every value of type Child is also a value of type Base (although not vice-versa). That means Child | Base is equivalent to Base... although the compiler is not always aggressive about reducing the former to the latter. (Compare this to the behavior with something like "foo" | string, which is always immediately reduced to string by the compiler.)

Subtype reduction is often desirable, but there are some places where Child | Base's behavior is observably different from Base's, such as excess property checks, IntelliSense hinting, or the sort of unsound type guarding that happens with the in operator. You haven't shown why it matters to you that you are getting a Base as opposed to a Child | Base, but presumably it's one of these observable differences or something like it.

My advice here is first to think carefully about whether or not you really need this distinction. If so, then you might consider preventing Base from being a subtype of Child, possibly by adding an optional property to it:

You could find all ages greater than zero:

Just add them to an array and check if the current author's ID is in that array:

I think lazy() method added in laravel version v8.34.0.Even if you are using Laravel 8 then make sure it should be at least version v8.34.0

As per Laravel Framework release note.
