Usage

infer_nanoarrow_ptype_extension(
  extension_spec,
  x,
  ...,
  warn_unregistered = TRUE
)

convert_array_extension(
  extension_spec,
  array,
  to,
  ...,
  warn_unregistered = TRUE
)

as_nanoarrow_array_extension(extension_spec, x, ..., schema = NULL)

Arguments

extension_spec

An extension specification inheriting from 'nanoarrow_extension_spec'.

x, array, to, schema, ...

Passed from infer_nanoarrow_ptype(), convert_array(), as_nanoarrow_array(), and/or as_nanoarrow_array_stream().

warn_unregistered

Use FALSE to infer/convert based on the storage type without a warning.

Value

• infer_nanoarrow_ptype_extension(): The R vector prototype to be used as the default conversion target.

• convert_array_extension(): An R vector of type to.

• as_nanoarrow_array_extension(): A nanoarrow_array of type schema.
