Recommendation questions about which tools, libraries or technologies to use or where to find them. I don't support this being on the off-topic list. (I found my way here from the comments on thi...
The hard part is figuring out exactly how your code needs to adapt to changes in the JSON structure. In your example, presumably the rest of your program needs to depend on the names and types in p...
For holding ordered sets of keys, there are well-known data structures (the red-black tree, for example) that support O(log(n)) lookup and insertion algorithms. Of course this means that there triv...
I hear the walk-before-we-run argument. I think this would be a good thing to try once we reach running speed, though. Personally, I don't like self-answered questions; I think they're an awkward f...
I think your edited post merits a new answer! You're right that you can make some sort of connection between addition, concatenation, and logical ‘and’—these are all operators that can be considere...
This error doesn't do a good job at all of highlighting the important thing! You can't define an inherent impl on a type parameter. You have to make it the impl of some trait. Here's an example: Tr...
tl;dr: No. From an engineering perspective, you might be asking if a concatenation operator can be used in place of a logical ‘and’ operator. This is obviously specific to a particular language, bu...
Okay, I'll be the contrarian. For this case, yes, I think a regex-based approach can be used to validate these properties. This approach will not guarantee that the provided input is valid HTML; in...
There is no fixed number of days in a MONTH interval. DATE_SUB is mostly just decrementing the number in the months position of the date provided. So DATE_SUB('2020-09-14', INTERVAL 3 MONTH) is '20...
