Enum parquet2::metadata::ColumnOrder

pub enum ColumnOrder {
    TypeDefinedOrder(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.

Variants

TypeDefinedOrder(SortOrder)

Column uses the order defined by its logical or physical type (if there is no logical type), parquet-format 2.4.0+.

Undefined

Undefined column order, means legacy behaviour before parquet-format 2.4.0. Sort order is always SIGNED.

Implementations

impl ColumnOrder

pub fn sort_order(&self) -> SortOrder

Returns sort order associated with this column order.

Trait Implementations

impl Clone for ColumnOrder

fn clone(&self) -> ColumnOrder

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColumnOrder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<ColumnOrder> for ColumnOrder

fn eq(&self, other: &ColumnOrder) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
