tspec_df errors on invalid names

Code
  (expect_error(tspec_df(x = tib_int("x"), x = tib_int("y"))))
Output
  <error/vctrs_error_names_must_be_unique>
  Error in `tspec_df()`:
  ! Names must be unique.
  x These names are duplicated:
    * "x" at locations 1 and 2.

tspec_df errors if element is not a tib collector

Code
  (expect_error(tspec_df(1)))
Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! ..1 must be a tib collector, not the number 1.
Code
  (expect_error(tspec_df(x = tib_int("x"), y = "a")))
Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! y must be a tib collector, not the string "a".

tspec_df can infer name from key

Code
  (expect_error(tspec_df(tib_int(c("a", "b")))))
Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! In field 1.
  Caused by error:
  ! `key` must be a single string to infer name.
  x `key` has length 2.
Code
  (expect_error(tspec_df(y = tib_int("x"), tib_int("y"))))
Output
  <error/vctrs_error_names_must_be_unique>

  ! Names must be unique.
  x These names are duplicated:
    * "y" at locations 1 and 2.

tspec_df errors on invalid .names_to

Code

Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! `.names_to` must be a single string or `NULL`, not a character `NA`.
Code
  (expect_error(tspec_df(.names_to = 1)))
Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! `.names_to` must be a single string or `NULL`, not the number 1.

tspec_df errors if .names_to column name is not unique

Code
  (expect_error(tspec_df(x = tib_int("x"), .names_to = "x")))
Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! The column name of `.names_to` is already specified in `...`.

tspec_df errors if .names_to is used with colmajor

Code
  (expect_error(tspec_df(.names_to = "x", .input_form = "colmajor")))
Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! Can't use `.names_to` with `.input_form = "colmajor"`.

tspec_df errors if vector_allows_empty_list is invalid

Code
  (expect_error(tspec_df(.vector_allows_empty_list = NA)))
Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! `.vector_allows_empty_list` must be `TRUE` or `FALSE`, not `NA`.
Code
  (expect_error(tspec_df(.vector_allows_empty_list = "a")))
Output
  <error/rlang_error>
  Error in `tspec_df()`:
  ! `.vector_allows_empty_list` must be `TRUE` or `FALSE`, not the string "a".

tspec_* can nest specifications

Code
  (expect_error(tspec_df(spec1, spec1)))
Output
  <error/vctrs_error_names_must_be_unique>
  Error in `tspec_df()`:
  ! Names must be unique.

Output
  <error/rlang_error>
