Struct RowNumber

pub struct RowNumber<'a> { /* private fields */ }

A window function that assigns a sequential integer number to each row in the query’s result set.

Implementations

impl<'a> RowNumber<'a>

pub fn order_by<T>(self, value: T) -> Self

where T: IntoOrderDefinition<'a>,

Define the order of the row number. Is the row order if not set.

pub fn partition_by<T>(self, partition: T) -> Self

where T: Into<Column<'a>>,

Define the partitioning of the row number

Trait Implementations

impl<'a> Clone for RowNumber<'a>

fn clone(&self) -> RowNumber<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for RowNumber<'a>

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

Formats the value using the given formatter.

impl<'a> Default for RowNumber<'a>

fn default() -> RowNumber<'a>

Returns the “default value” for a type.

impl<'a> PartialEq for RowNumber<'a>

fn eq(&self, other: &RowNumber<'a>) -> 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.
