---------------------------------------
Summary: [R] Expose C interface as R6 methods
Key: ARROW-12940
URL: https://issues.apache.org/jira/browse/ARROW-12940
Project: Apache Arrow
Issue Type: New Feature
Components: R
Reporter: Neal Richardson
Assignee: Jonathan Keane
Fix For: 5.0.0
Similar to pyarrow's export_to_c and import_from_c methods. We have c++
wrappers like ImportRecordBatch but they aren't exported from the package
namespace, so attaching them to the R6 objects would provide a way to do that.
Lifecycle management of the C pointers they read/write to (allocate/delete) is
left outside of these methods (as it is in the non-exported wrappers today).
export_to_c should be a method on an object. import_from_c should be a "class
method" like {{$create()}}.
Once this is done, we should inform duckdb of this so that they can remove
their {{getFromNamespace()}} workaround.
