Functions ¶
func TryConvertToMarshalMap ¶
TryConvertToMarshalMap converts collections to MarshalMap if possible. This is a deep conversion, i.e. each element in the collection will be traversed. You can pass a formatKey function that will be applied to all string keys that are detected.

type MarshalMap ¶
type MarshalMap map[string]interface{}
MarshalMap is a wrapper type to attach converter methods to maps normally returned by marshalling methods, i.e. key/value parsers. All methods that do a conversion will return an error if the value stored behind key is not of the expected type or if the key is not existing in the map.

Examples: "key" -> mmap["key"] single value "key1/key2" -> mmap["key1"]["key2"] nested map "key1[0]" -> mmap["key1"][0] nested array "key1[0]key2" -> mmap["key1"][0]["key2"] nested array, nested map
