# Which issue does this PR close? Part of #5781 # Rationale for this change We are in the process of allowing users to define their own window functions, and to do we plan for them to implement the `PartitionEvaluator` trait, similarly to how they implement the `Accumulator` trait for aggregates You can see the basic idea in the RFC PR: #6617 I think this is the last "getting ready" PR and the next one will have real support for User Defined Window Functions 🤞 # What changes are included in this PR? Move `PartitionEvaluator` and related structures to `datafusion_expr` crate (where the WindowUDFs will be defined) There is no new functionality, this PR just moves code around. # Are these changes tested? Covered by existing tests # Are there any user-facing changes? `PartitionEvaluator` and related structs are now visible in `datafusion_expr` -- This is an automated message from the Apache Git Service.
