Functions

• all_streamable
• is_streamable
• lit
  Create a Literal Expression from L. A literal expression behaves like a column that contains a single distinct value.
• node_to_expr
  converts a node from the AExpr arena to Expr
• node_to_lp
  converts a node from the IR arena to a LogicalPlan
• node_to_lp_cloned
• optimize
• set_estimated_row_countsstreaming
• to_aexpr
  converts expression to AExpr and adds it to the arena, which uses an arena (Vec) for allocation
• to_alp
• to_alp_impl
  converts LogicalPlan to IR it adds expressions & lps to the respective arenas as it traverses the plan finally it returns the top node of the logical plan
• to_expr_ir
• to_expr_ir_ignore_alias
• typed_lit
