# Which issue does this PR close? Resolves https://github.com/apache/arrow-datafusion/issues/1014 # Rationale for this change We would like to order `Expr`s in a consistent way in our tests. See details on https://github.com/influxdata/influxdb_iox/pull/2564 in https://github.com/influxdata/influxdb_iox/pull/2564#discussion_r710817261 This also is a necessary (but not sufficient) step towards being able to use `Expr`s in sets and maps (still need to implement `Ord` and `Hash`) which might have helped @waynexia in https://github.com/apache/arrow-datafusion/pull/792 with CSE and would help with other algebriac transformations in the future. # What changes are included in this PR? ```rust impl PartialOrd` for `Expr` ``` # Are there any user-facing changes? Can now compare Exprs -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
