Struct OrderKey 

pub struct OrderKey {
    pub column: usize,
    pub ascending: bool,
}

A single ORDER BY key inside an OVER (... ORDER BY ...) clause.

Fields

column: usize

Column index (position into the columnar row model).

ascending: bool

true for ASC, false for DESC.

Implementations

impl OrderKey

pub fn asc(column: usize) -> Self

Construct an ascending order key on column.

pub fn desc(column: usize) -> Self

Construct a descending order key on column.

Trait Implementations

impl Clone for OrderKey

fn clone(&self) -> OrderKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderKey

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

Formats the value using the given formatter.

impl PartialEq for OrderKey

fn eq(&self, other: &OrderKey) -> 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.
