Types¶
typeFunctionOp¶
FunctionOp is a function with accepts zero or more arguments and producesa value or error as a result.
typeOverload¶
type Overload struct {// Operator name as written in an expression or defined within// operators.go.Operatorstring// Operand trait used to dispatch the call. The zero-value indicates a// global function overload or that one of the Unary / Binary / Function// definitions should be used to execute the call.OperandTraitint// Unary defines the overload with a UnaryOp implementation. May be nil.UnaryUnaryOp// Binary defines the overload with a BinaryOp implementation. May be nil.BinaryBinaryOp// Function defines the overload with a FunctionOp implementation. May be// nil.FunctionFunctionOp// NonStrict specifies whether the Overload will tolerate arguments that// are types.Err or types.Unknown.NonStrictbool}Overload defines a named overload of a function, indicating an operand traitwhich must be present on the first argument to the overload as well as oneof either a unary, binary, or function implementation.
The majority of operators within the expression language are unary or binaryand the specializations simplify the call contract for implementers oftypes with operator overloads. Any added complexity is assumed to be handledby the generic FunctionOp.
