// InvalidParameterError is returned if invalid parameters are encountered. This
// error specifically refers to situations where parameters are non-empty but
// have an invalid syntax/format. The error message includes the function
// that returned the error originally and the parameter type that was deemed
// invalid.
//
// Example:
//
// // err is of type InvalidParameterError
// _, err := expression.Name("foo..bar").BuildOperand()
type InvalidParameterError struct {
parameterType string
functionName string
}

// UnsetParameterError is returned if parameters are empty and uninitialized.
// This error is returned if opaque structs (ConditionBuilder, NameBuilder,
// Builder, etc) are initialized outside of functions in the package, since all
// structs in the package are designed to be initialized with functions.
//
// Example:
//
// // err is of type UnsetParameterError
// _, err := expression.Builder{}.Build()
// _, err := expression.NewBuilder().
// WithCondition(expression.ConditionBuilder{}).
// Build()
type UnsetParameterError struct {
parameterType string
functionName string

You can’t perform that action at this time.
