ryzhyk opened a new pull request, #14863: URL: https://github.com/apache/datafusion/pull/14863
## Which issue does this PR close? - Closes #14862 ## Rationale for this change When datafusion is used in a workspace that enables the `rkyv-64` feature in the `chrono` crate, this triggered a Rust compilation error: ``` error[E0277]: can't compare `Option<&std::string::String>` with `Option<&mut std::string::String>`. ``` The root cause of the error is incorrect type unification in the Rust compiler, as explained in https://github.com/rkyv/rkyv/issues/434. ## What changes are included in this PR? The workaround pushes the compiler in the right direction by converting the mutable reference to an immutable one manually. ## Are these changes tested? I don't think this requires additional tests. ## Are there any user-facing changes? no -- This is an automated message from the Apache Git Service.
