Struct datafusion_physical_expr::PhysicalSortExpr

pub struct PhysicalSortExpr {
    pub expr: Arc<dyn PhysicalExpr>,
    pub options: SortOptions,
}

Represents Sort operation for a column in a RecordBatch

Fields

expr: Arc<dyn PhysicalExpr>

Physical expression representing the column to sort

options: SortOptions

Option to specify how the given column should be sorted

Implementations

impl PhysicalSortExpr

pub fn evaluate_to_sort_column(&self, batch: &RecordBatch) -> Result<SortColumn>

evaluate the sort expression into SortColumn that can be passed into arrow sort kernel

Trait Implementations

impl Clone for PhysicalSortExpr

fn clone(&self) -> PhysicalSortExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PhysicalSortExpr

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

Formats the value using the given formatter.

impl Display for PhysicalSortExpr

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

Formats the value using the given formatter.

impl PartialEq<PhysicalSortExpr> for PhysicalSortExpr

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