Module sort_properties

Source

Structs§

  • Represents the properties of a PhysicalExpr, including its sorting and range attributes.

Enums§

  • To propagate SortOptions across the PhysicalExpr, it is insufficient to simply use Option<SortOptions>: There must be a differentiation between unordered columns and literal values, since literals may not break the ordering when they are used as a child of some binary expression when the other child has some ordering. On the other hand, unordered columns cannot maintain ordering when they take part in such operations.
