In DavisVaughan/slurrr: Sliding Window Functions

size of each .f result must be 1

Code
  slide_index_vec(1:2, 1:2, ~ c(.x, 1))
Condition
  Error:
  i In index: 1
  ! The result of `.f` must have size 1, not 2.

Code
  slide_index_dbl(1:2, 1:2, ~ c(.x, 1))
Condition
  Error:
  i In index: 1
  ! The result of `.f` must have size 1, not 2.

inner type can be restricted with list_of

Code
  (expect_error(slide_index_vec(1:2, 1:2, ~ if (.x == 1L) {
    list_of(1)
  } else {
    list_of("hi")
  }, .ptype = list_of(.ptype = double())), class = "vctrs_error_incompatible_type")
  )
Output
  <error/vctrs_error_cast>
  Error in `slide_index_vec()`:
  ! Can't convert `..1` <character> to <double>.

type of suffixed versions can be restricted

Code
  (expect_error(slide_index_dbl(1:2, 1:2, ~ if (.x == 1L) {
    1
  } else {
    "hi"
  }), class = "vctrs_error_incompatible_type"))
Output
  <error/vctrs_error_cast>
  Error:
  ! Can't convert <character> to <double>.

.ptype is respected

Code
  (expect_error(slide_index_vec(1, 1, ~ .x + 0.5, .ptype = integer()), class = "vctrs_error_cast_lossy")
  )
Output
  <error/vctrs_error_cast_lossy>
  Error in `slide_index_vec()`:
  ! Can't convert from `out[[1]]` <double> to <integer> due to loss of precision.
  * Locations: 1

.ptype = NULL fails if no common type is found

Code
  (expect_error(slide_index_vec(1:2, 1:2, ~ ifelse(.x == 1L, "hello", 1), .ptype = NULL),
  class = "vctrs_error_incompatible_type"))
Output
  <error/vctrs_error_ptype2>
  Error in `slide_index_vec()`:
  ! Can't combine `out[[1]]` <character> and `out[[2]]` <double>.

.ptype = NULL validates that element lengths are 1

Code
  slide_index_vec(1:2, 1:2, ~ if (.x == 1L) {
    1:2
  } else {
    1
  }, .ptype = NULL)
Condition
  Error:
  i In index: 1
  ! The result of `.f` must have size 1, not 2.

slide_index_chr() cannot coerce

Code
  (expect_error(slide_index_chr(1, 1, ~.x), class = "vctrs_error_incompatible_type")
  )
Output
  <error/vctrs_error_cast>
  Error:
  ! Can't convert <double> to <character>.
