romainfrancois opened a new pull request #11751:
URL: https://github.com/apache/arrow/pull/11751
This adds `$code()` to `DataType` objects in R, which is then used by
`Schema$code()`.
In both case, `$code()` produces an R call, e.g.
``` r
library(arrow, warn.conflicts = FALSE)
#> See arrow_info() for available features
int32()$code()
#> int32()
struct(a = timestamp())$code()
#> struct(a = timestamp(unit = "s"))
schema(
a = float64(),
b = list_of(large_utf8()),
c = struct(
d = fixed_size_binary(byte_width = 7L),
e = null()
)
)$code()
#> schema(a = float64(), b = list_of(large_utf8()), c = struct(d =
fixed_size_binary(byte_width = 7L),
#> e = null()))
```
