Convert an object to a nanoarrow buffer
Examples
array <- as_nanoarrow_array(c(NA, 1:4))
array$buffers
#> [[1]]
#> <nanoarrow_buffer validity<bool>[8][1 b]> `FALSE TRUE TRUE TRUE TRUE FALSE F...`
#>
#> [[2]]
#> <nanoarrow_buffer data<int32>[5][20 b]> `NA 1 2 3 4`
#>
as.raw(array$buffers[[1]])
#> [1] 1e
as.raw(array$buffers[[2]])
#> [1] 00 00 00 80 01 00 00 00 02 00 00 00 03 00 00 00 04 00 00 00
convert_buffer(array$buffers[[1]])
#> [1] FALSE TRUE TRUE TRUE TRUE FALSE FALSE FALSE
convert_buffer(array$buffers[[2]])
#> [1] NA 1 2 3 4
