Module predicate

Macros

• return_none_if_utf8 🔒
  Assert the scalar value is not utf8. Returns None if it’s utf8. In theory, it should be converted to a timestamp scalar value by TypeConversionRule.

Structs

• Predicate
  Reference-counted pointer to a list of logical exprs.

Functions

• build_time_range_predicate
  build_time_range_predicate extracts time range from logical exprs to facilitate fast time range pruning.
• extract_from_between_expr 🔒
• extract_from_binary_expr 🔒
• extract_from_in_list_expr 🔒
  Extract time range filter from IN (...) expr.
• extract_time_range_from_expr 🔒
  Extract time range filter from WHERE/IN (...)/BETWEEN clauses. Return None if no time range can be found in expr.
• get_timestamp_filter 🔒
