`missing` is validated

Code
  (expect_error(vec_interval_locate_groups(1, 2, missing = "s")))
Output
  <error/rlang_error>
  Error in `vec_interval_locate_groups()`:
  ! `missing` must be either "group" or "drop".

Code
  (expect_error(vec_interval_locate_groups(1, 2, missing = c("group", "drop"))))
Output
  <error/rlang_error>
  Error in `vec_interval_locate_groups()`:
  ! `missing` must be a string.

common type is taken

Code
  (expect_error(vec_interval_locate_groups(1, "x")))
Output
  <error/vctrs_error_ptype2>
  Error:
  ! Can't combine `start` <double> and `end` <character>.

Code
  (expect_error(vec_interval_locate_containers(1, "x")))
Output
  <error/vctrs_error_ptype2>
  Error:
  ! Can't combine `start` <double> and `end` <character>.

`lower` and `upper` can't contain missing values

Code
  (expect_error(vec_interval_complement(1, 2, lower = NA)))
Output
  <error/rlang_error>
  Error in `vec_interval_complement()`:
  ! `lower` can't contain missing values.

Code
  start <- data_frame(x = 1, y = 2)
