vec_detect_complete() detects "complete" observations. An observation is
considered complete if it is non-missing. For most vectors, this implies that
vec_detect_complete(x) == !vec_detect_missing(x).
For data frames and matrices, a row is only considered complete if all
elements of that row are non-missing. To compare,
detects rows that are partially complete (they have at least one non-missing
A record type vector is similar to a data frame, and is only considered complete if all fields are non-missing.
