I have an API that behaves along the following lines:

Is there a way (except looking at implementation and docs) to determine when new() in rust allocates on stack or heap?

Ideally I'm looking for a way to determine this when writing source at a glance. For example trait or parameter that can be added restricting whether heap allocation can take place.

Working with type stubs, I'm wondering if it's possible to express a type in Python that allows you to type this correctly for any number of arguments:

The challenge is to find the number between "produto_id:" and the last character, which is sometimes a "]" or a " , ". When it's a "]", it does extract the text, but it doesn't when it's a comma.

The cell value:

If I run the code below, my Global Environment in RStudio tells me the dimensions for x2 (num [1:10, 1:10, 1:10]). But for x1, it only says "large array (1000000 elements, 7.6 Mb)".

I want to see the array's dimensions at a glance even for large arrays. (I know I can run dim(x1) to get the dimensions, looking for an "at a glance" solution with RStudio...)

Is there a way to get RStudio to treat even large arrays like it does with smaller arrays?

EDIT: It does show the dimensions if I click the small blue error beside x1, but I'm working with many large arrays and adding/removing from my environment. I am hoping to make it show the dimensions by default.

I'm trying to figure out how to parse S-expressions in C on my own, in order to store data and code for my own rudimentary Lisp (written as a learning exercise, not for production).

Before explaining my code and my reasoning, I should explain that all I know about S-expressions is the introductory section of the Wikipedia article on it, and the occasional glance at Common Lisp code, so the naming of my structs and variables may be a bit off.

My language of implementation is C, and before I defined any functions I created the following structs:

I try example in this topic https://github.com/DevExpress-Examples/XPO_how-to-create-an-xpclassinfo-descendant-to-dynamically-build-a-persistent-class-structure-e1729

But It only works for single primary key tables. So i searched more Found this: https://github.com/DevExpress-Examples/XPO_how-to-create-persistent-classes-mapped-to-tables-with-a-composite-primary-key-at-runtime-e4606

Buts there's big different and I think its not satisfy because it speaking about composite key( one Key which have many columns) So all I need please an example of creating XPO dynamically from SQL -Server Table: My Table Schema as following

The XPOCollectionSource then binding to grid in server-mode… Thats all I need.

Code I Use

I have run 3 regressions with rdrobust, and would like to print some of the values (not all of them in a table, so that each model has a column and the results can be compared side by side.

I tried with stargazer but with no success, same thing goes for modelsummary.

This is what my regression code looks like:

I use a spreadsheet to prioritize workflow for my team. Certain cells highlight depending on how close we are to cycle times. There is a start date, a tentative finish date, and a discharge date.

A blank discharge date cell turns red if: start date is not blank; tentative is not blank; and today's date is within five days of the tentative date.

Some of my team member have the habit of writing their dates with periods (mm.dd.yyyy). Excel of course does not recognize this as a date. BUT it does know that the 'tentative date' cell is not blank. As a result, even if today's date is equal to the tentative date, the 'discharge date' cell does not turn red. This is taking away from the utility of this sheet, as it is intended to be info at a glance, where a glaring red cell lets one know, "Oh shoot! I need to focus on that task as a priority."

I'd like for the start date and tentative date cells to go red if the date is not the desired format (mm/dd/yyyy).

Formula and condition in S1:

S1 fills red if

=AND($P1-TODAY()<=5,COUNTA($S1)=0,$M1<>0,$P1<>0)
