Module simplify_expressions

SimplifyExpressions simplifies expressions in the logical plan, ExprSimplifier simplifies individual Exprs.

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

• DEFAULT_MAX_SIMPLIFIER_CYCLES
• THRESHOLD_INLINE_INLIST

Traits

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