Coercion rules for matching argument types for binary operators

Functions

  • comparison_coercion
    Coerce lhs_type and rhs_type to a common type for the purposes of a comparison operation
  • get_input_types
    Returns the coerced input types for a binary expression evaluating the op with the left and right hand types
  • get_result_type
    returns the resulting type of a binary expression evaluating the op with the left and right hand types
  • get_wider_type
    Returns the wider type among arguments lhs and rhs. The wider type is the type that can safely represent values from both types without information loss. Returns an Error if types are incompatible.
  • like_coercion
    coercion rules for like operations. This is a union of string coercion rules and dictionary coercion rules
  • regex_coercion
    coercion rules for regular expression comparison operations. This is a union of string coercion rules and dictionary coercion rules
