Module physical_expr

Traits

• DynEq
  PhysicalExpr can’t be constrained by Eq directly because it must remain object safe. To ease implementation blanket implementation is provided for Eq types.
• DynHash
  PhysicalExpr can’t be constrained by Hash directly because it must remain object safe. To ease implementation blanket implementation is provided for Hash types.
• PhysicalExpr
  PhysicalExprs represent expressions such as A + 1 or CAST(c1 AS int).

Functions

• down_cast_any_refDeprecated
• format_physical_expr_list
  Returns Display able a list of PhysicalExpr
• with_new_children_if_necessary
  Returns a copy of this expr if we change any child according to the pointer comparison. The size of children must be equal to the size of PhysicalExpr::children().
