URL: https://github.com/apache/arrow/issues/35604
### Describe the bug, including details regarding any error messages,
version, and platform.
When reading a parquet file and trying to set the schema to use a struct, I
only get NA values back.
```r
# write parquet
arrow::write_dataset(iris, path = 'iris.parquet')
arrow::open_dataset("iris.parquet") |> dplyr::collect()
Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1 5.1 3.5 1.4 0.2 setosa
2 4.9 3.0 1.4 0.2 setosa
arrow::open_dataset("iris.parquet", schema = schema(Species=string(),
Sepal =
struct(Sepal.Length = float64(), Sepal.Width = float64()),
Petal =
struct(Petal.Length = float64(), Petal.Width = float64()))) |>
dplyr::collect()
Species Sepal$Sepal.Length $Sepal.Width Petal$Petal.Length $Petal.Width
<chr> <dbl> <dbl> <dbl> <dbl>
1 setosa NA NA NA NA
2 setosa NA NA NA NA
3 setosa NA NA NA NA
> packageVersion('arrow')
