Modules

expr_simplifier

Expression simplification API

simplify_exprs

Simplify expressions optimizer rule and implementation

Structs

ExprSimplifier

This structure handles API for expression simplification

GuaranteeRewriter

Rewrite expressions to incorporate guarantees.

SimplifyContext

Provides simplification information based on DFSchema and ExecutionProps. This is the default implementation used by DataFusion

SimplifyExpressions

Optimizer Pass that simplifies LogicalPlans by rewriting Expr`s evaluating constants and applying algebraic simplifications

Constants

Traits

SimplifyInfo

Provides the information necessary to apply algebraic simplification to an Expr. See SimplifyContext for one concrete implementation.
