The rcrd class extends vctr. A rcrd is composed of 1 or more fields, which must be vectors of the same length. Is designed specifically for classes that can naturally be decomposed into multiple vectors of the same length, like POSIXlt, but where the organisation should be considered an implementation detail invisible to the user (unlike a data.frame).
new_rcrd(fields, ..., class = character())A list or a data frame. Lists must be rectangular
(same sizes), and contain uniquely named vectors (at least
one). fields is validated with df_list() to ensure uniquely
named vectors.
