func MarshalJSONEnum(m map[int32]string, value int32) ([]byte, error)

func UnmarshalJSONEnum ¶

func UnmarshalJSONEnum(m map[string]int32, data []byte, enumName string) (int32, error)

UnmarshalJSONEnum is a helper function to simplify recovering enum int values from their JSON-encoded representation. Given a map from the enum's symbolic names to its int values, and a byte buffer containing the JSON-encoded value, it returns an int32 that can be cast to the enum type by the caller.

The function can deal with both JSON representations, numeric and symbolic.
