Register registers a parsing function for name that will be used to unmarshal a JSON message into the appropriate modifier.

Types

type ErrUnknownModifier

type ErrUnknownModifier struct {
	// contains filtered or unexported fields
}

ErrUnknownModifier is the error returned when the message does not contain a field representing a known modifier type.

func (ErrUnknownModifier) Error

	Response ModifierType = "response"
)

type Result

type Result struct {
	// contains filtered or unexported fields
}

func FromJSON

func FromJSON(b []byte) (*Result, error)

FromJSON parses a Modifier JSON message by looking up the named modifier in parseFuncs and passing its modifier to the registered parseFunc.
