Enum SortOrder

pub enum SortOrder {
    SIGNED,
    UNSIGNED,
    UNDEFINED,
}

Sort order for page and column statistics.

Types are associated with sort orders and column stats are aggregated using a sort order, and a sort order should be considered when comparing values with statistics min/max.

See reference in https://github.com/apache/arrow/blob/main/cpp/src/parquet/types.h

Variants

SIGNED

Signed (either value or legacy byte-wise) comparison.

UNSIGNED

Unsigned (depending on physical type either value or byte-wise) comparison.

UNDEFINED

Comparison is undefined.

Implementations

impl SortOrder

pub fn is_signed(&self) -> bool

Returns true if this is Self::SIGNED

Trait Implementations

impl Clone for SortOrder

fn clone(&self) -> SortOrder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SortOrder

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

Formats the value using the given formatter.

impl Display for SortOrder

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

Formats the value using the given formatter.

impl PartialEq for SortOrder

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for SortOrder

impl Eq for SortOrder

impl StructuralPartialEq for SortOrder
