Hi 👋 I’d like to take this issue and want to double-check my understanding of the desired behavior for nw.struct(...). I’ve been exploring different representations of “struct-like” outputs in Pandas...

Hi @danielgafni, thanks for the clarification! Just to explain where I was coming from: since I’m still new to struct types, I started with Pandas only to better understand the...

Hi! Here’s an update on nw.struct(...) `nw.struct("a", "b", "c")` **Top-level constructor** - [x] I’ve implemented the struct(...) function to be in functions.py: ``` python # struct() constructor function # to...

So far this is what this PR does, I'll attempt polars/arrow next: ```python df_native_pd = pd.DataFrame({ "a": [1, 2, 3], "b": ["x", "y", "z"], "c": [True, False, True], }) df_pd...

At this point, we also get these results for polars df and arrow tables: **Polars**: ``` python df_native_pl = pl.DataFrame({ "a": [1, 2, 3], "b": ["x", "y", "z"], "c": [True,...

I have started with the tests. I see that there are more backends than pandas, polars and arrow. ``` (narwhals) ➜ narwhals git:(issue_3247) ✗ pytest tests/expr_and_series/concat_struct_test.py -v -k dryrun --tb=no...

Hi, Thanks for the clarification @FBruzzesi, I totally get it now! I have changed all `concat_struct` references to `struct`.
