Examples

nanoarrow_extension_array(1:10, "some_ext", '{"key": "value"}')
#> <nanoarrow_array some_ext{int32}[10]>
#>  $ length    : int 10
#>  $ null_count: int 0
#>  $ offset    : int 0
#>  $ buffers   :List of 2
#>   ..$ :<nanoarrow_buffer validity<bool>[null] ``
#>   ..$ :<nanoarrow_buffer data<int32>[10][40 b]> `1 2 3 4 5 6 7 8 9 10`
#>  $ dictionary: NULL
#>  $ children  : list()
