1	pass_arrow_record_batch(srb)

srb

a raw vector representing the contents of an IPC buffer

The majority of the work here is being done by the RecordBatches struct and associated functions that transform a serialized RecordBatch (raw vector) into RecordBatches and back to a serialized RecordBatch using the IPC specification.

RecordBatches to be serialized back to an IPC buffer

mtcars_rb <- arrow::record_batch(mtcars)
mtcars_out <- arrow::write_to_raw(mtcars_rb, "stream")
mtcars_in_buffer <- as.raw(pass_arrow_record_batch(mtcars_out))
mtcars_in <- arrow::read_ipc_stream(mtcars_in_buffer)
