Driver Example
==============

.. recipe:: recipe_driver/driver_example.cc

Low-level testing
=================

.. recipe:: recipe_driver/driver_example_test.cc

High-level testing
==================

.. recipe:: recipe_driver/driver_example.py

High-level tests can also be written in R using the ``adbcdrivermanager``
package.

.. code-block:: r

   library(adbcdrivermanager)

   drv <- adbc_driver("build/libdriver_example.dylib")
   db <- adbc_database_init(drv, uri = paste0("file://", getwd()))
   con <- adbc_connection_init(db)

   data.frame(col = 1:3) |> write_adbc(con, "example.arrows")
   con |> read_adbc("SELECT * FROM example.arrows") |> as.data.frame()
   unlink("example.arrows")

Driver Manifests
================

.. recipe:: recipe_driver/driver_example_manifest.py

Driver manifests can provide an easier way to install and manage ADBC drivers,
via TOML files that describe some metadata along with the path to the driver
shared library. The driver manager can read these manifests to locate and load
drivers dynamically.
