Module datafusion_expr::type_coercion::binary

Coercion rules for matching argument types for binary operators

Functions

• binary_operator_data_type
  Returns the return type of a binary operator or an error when the binary operator cannot perform the computation between the argument’s types, even after type coercion.
• coerce_types
  Coercion rules for all binary operators. Returns the output type of applying op to an argument of lhs_type and rhs_type.
• comparison_coercion
  Returns the output type of applying comparison operations such as eq, not eq, lt, lteq, gt, and gteq to arguments of lhs_type and rhs_type.
• 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
• temporal_add_sub_coercion
