- forWriting() : self
- fromThrift() : self
- isTrusted() : bool
- toThrift() : ColumnOrder
- trustedMax() : bool|float|int|string|null
- The statistics max a reader may use, null when it may not. Under TYPE_DEFINED_ORDER a floating point max of NaN is ignored and a -0.0 max may hide +0.0 values (parquet.thrift ColumnOrder).
- trustedMin() : bool|float|int|string|null
- The statistics min a reader may use, null when it may not. Under TYPE_DEFINED_ORDER a floating point min of NaN is ignored and a +0.0 min may hide -0.0 values (parquet.thrift ColumnOrder).
