%description
Provides an 'R' interface to the 'nanoarrow' 'C' library and the 'Apache
Arrow' application binary interface. Functions to import and export
'ArrowArray', 'ArrowSchema', and 'ArrowArrayStream' 'C' structures to and
from 'R' objects are provided alongside helpers to facilitate zero-copy
data transfer among 'R' bindings to libraries implementing the 'Arrow' 'C'
data interface.
