relationship default behavior is correct

Code
  out <- join_rows(c(1, 1), c(1, 1), condition = "==")
Condition
  Warning:
  Detected an unexpected many-to-many relationship between `x` and `y`.
  i Row 1 of `x` matches multiple rows in `y`.
  i Row 1 of `y` matches multiple rows in `x`.
  i If a many-to-many relationship is expected, set `relationship = "many-to-many"` to silence this warning.

join_rows() allows unmatched to be specified independently for inner joins

Code
  join_rows(c(1, 3), c(1, 2), type = "inner", unmatched = c("drop", "error"))
Condition
  Error:
  ! Each row of `y` must be matched by `x`.
  i Row 2 of `y` was not matched.

join_rows() expects incompatible type errors to have been handled by join_cast_common()

Code
  (expect_error(join_rows(data.frame(x = 1), data.frame(x = factor("a")))))
Output
  <error/rlang_error>
  Error:
  ! `join_cast_common()` should have handled this.
  i This is an internal error that was detected in the dplyr package.
    Please report it at <https://github.com/tidyverse/dplyr/issues> with a reprex (<https://tidyverse.org/help/>) and the full backtrace.

join_rows() gives meaningful one-to-one errors

Code
  join_rows(1, c(1, 1), relationship = "one-to-one")
Condition
  Error:
  ! Each row in `x` must match at most 1 row in `y`.
  i Row 1 of `x` matches multiple rows in `y`.

Code
  join_rows(c(1, 1), 1, relationship = "one-to-one")
Condition
  Error:
  ! Each row in `y` must match at most 1 row in `x`.
  i Row 1 of `y` matches multiple rows in `x`.

join_rows() gives meaningful one-to-many errors

Code
  join_rows(c(1, 1), 1, relationship = "one-to-many")
Condition
  Error:
  ! Each row in `y` must match at most 1 row in `x`.
  i Row 1 of `y` matches multiple rows in `x`.

join_rows() gives meaningful many-to-one errors

Code
  join_rows(1, c(1, 1), relationship = "many-to-one")
Condition
  Error:
  ! Each row in `x` must match at most 1 row in `y`.
  i Row 1 of `x` matches multiple rows in `y`.

join_rows() gives meaningful many-to-many warnings

Code
  join_rows(c(1, 1), c(1, 1))
Condition
  Warning:
  Detected an unexpected many-to-many relationship between `x` and `y`.
  i Row 1 of `x` matches multiple rows in `y`.
  i Row 1 of `y` matches multiple rows in `x`.
  i If a many-to-many relationship is expected, set `relationship = "many-to-many"` to silence this warning.
Output
  $x
  [1] 1 1 2 2

  $y
  [1] 1 2 1 2

Code
  left_join(df, df, by = join_by(x))
Condition
  Warning in `left_join()`:
  Detected an unexpected many-to-many relationship between `x` and `y`.
  i Row 1 of `x` matches multiple rows in `y`.
  i Row 1 of `y` matches multiple rows in `x`.
  i If a many-to-many relationship is expected, set `relationship = "many-to-many"` to silence this warning.
Output
    x
  1 1
  2 1
  3 1
  4 1
