pub enum ColumnOrder {
TYPE_DEFINED_ORDER(SortOrder),
UNDEFINED,
}
Column order that specifies what method was used to aggregate min/max values for
statistics.
If column order is undefined, then it is the legacy behaviour and all values should
be compared as signed values/bytes.
Column uses the order defined by its logical or physical type
(if there is no logical type), parquet-format 2.4.0+.
Undefined column order, means legacy behaviour before parquet-format 2.4.0.
Sort order is always SIGNED.
Returns sort order for a physical/logical type.
Returns sort order associated with this column order.

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
