Struct datafusion_physical_expr::AnalysisContext

pub struct AnalysisContext {
    pub column_boundaries: Vec<Option<ExprBoundaries>>,
}

The shared context used during the analysis of an expression. Includes the boundaries for all known columns.

Fields

column_boundaries: Vec<Option<ExprBoundaries>>

A list of known column boundaries, ordered by the index of the column in the current schema.

Implementations

impl AnalysisContext

pub fn new(
    input_schema: &Schema,
    column_boundaries: Vec<Option<ExprBoundaries>>
) -> Self

pub fn from_statistics(input_schema: &Schema, statistics: &Statistics) -> Self

Create a new analysis context from column statistics.

Trait Implementations

impl Clone for AnalysisContext

fn clone(&self) -> AnalysisContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AnalysisContext

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

Formats the value using the given formatter.

impl PartialEq<AnalysisContext> for AnalysisContext

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