inputs must be named

Code
  vec_expand_grid(1)
Condition
  Error in `vec_expand_grid()`:
  ! All inputs must be named.

Code
  vec_expand_grid(x = 1, 2, y = 3)
Condition
  Error in `vec_expand_grid()`:
  ! All inputs must be named.

catches duplicate names by default

Code
  vec_expand_grid(a = 1, a = 2)
Condition
  Error in `vec_expand_grid()`:
  ! Names must be unique.
  x These names are duplicated:
    * "a" at locations 1 and 2.
  i Use argument `.name_repair` to specify repair strategy.

errors on non vectors and mentions the element name

Code
  vec_expand_grid(y = environment())
Condition
  Error in `vec_expand_grid()`:
  ! `y` must be a vector, not an environment.

can adjust the .error_call

Code
  my_expand_grid()
Condition
  Error in `my_expand_grid()`:
  ! `x` must be a vector, not an environment.

errors nicely when expansion results in a size larger than R_len_t

Code
  vec_expand_grid(x = x, y = y)
Condition
  Error in `vec_expand_grid()`:
  ! Long vectors are not yet supported. Expansion results in an allocation larger than 2^31-1 elements. Attempted allocation size was 3221225469.

errors nicely when expansion results in a size larger than R_xlen_t

Code
  vec_expand_grid(x = x, y = x)
Condition
  Error in `vec_expand_grid()`:
  ! Result too large for an `r_ssize`.
  i In file './rlang/c-utils.h' at line <scrubbed>.
  i This is an internal error that was detected in the vctrs package.
    Please report it at <https://github.com/r-lib/vctrs/issues> with a reprex (<https://tidyverse.org/help/>) and the full backtrace.

validates .vary

Code
  vec_expand_grid(.vary = 1)
Condition
  Error in `vec_expand_grid()`:
  ! `.vary` must be a string or character vector.

Code
  vec_expand_grid(.vary = "x")
Condition
  Error in `vec_expand_grid()`:
  ! `.vary` must be one of "slowest" or "fastest", not "x".
