[Not for merge] Make `ConvertedType` optional in the Parquet schema by etseidl · Pull Request #9980 · apache/arrow-rs

etseidl · 2026-05-15T19:41:49Z

Which issue does this PR close?

Closes #NNN.

Rationale for this change

Test of making converted type an optional field (as it is in the Parquet spec).

What changes are included in this PR?

Convert converted_type in the BasicTypeInfo to an Option<ConvertedType>, remove the ConvertedType::NONE variant (which is not in the spec).

Are these changes tested?

Are there any user-facing changes?
