Traits and types for reusable expression analysis

Re-exports§

Modules§

Structs§

  • Analysis that determines the number of columns of relation expressions.
  • Compute the estimated cardinality of each subtree of a MirRelationExpr from the bottom up.
  • Compute the column types of each subtree of a MirRelationExpr from the bottom-up.
  • Analysis that determines if all accumulations at all times are non-negative.
  • Analysis that determines the type of relation expressions.
  • Analysis that determines the unique keys of relation expressions.

Enums§

  • An abstract type denoting an inferred column name.

Traits§

  • An analysis that can be applied bottom-up to a MirRelationExpr.
  • Lattice methods for repeated analysis
