Functions ¶
func Atoi ¶
Atoi converts string to a number in a given base. Base should be either 10 or 16. It uses `atoi` method of StdLib native contract.
func Base58Decode ¶
Base58Decode calls `base58Decode` method of StdLib native contract and decodes given base58 string represented as a byte slice into a new byte slice.
func Base58Encode ¶
Base58Encode calls `base58Encode` method of StdLib native contract and encodes given byte slice into a base58 string and returns byte representation of this string.
func Base64Decode ¶
Base64Decode calls `base64Decode` method of StdLib native contract and decodes given base64 string represented as a byte slice into byte slice.
func Base64Encode ¶
Base64Encode calls `base64Encode` method of StdLib native contract and encodes given byte slice into a base64 string and returns byte representation of this string.
func Deserialize ¶
func Deserialize(b []byte) interface{}
Deserialize calls `deserialize` method of StdLib native contract and unpacks previously serialized value from a byte slice, it's the opposite of Serialize.
func Itoa ¶
Itoa converts num in a given base to string. Base should be either 10 or 16. It uses `itoa` method of StdLib native contract.
func JSONDeserialize ¶
func JSONDeserialize(data []byte) interface{}
JSONDeserialize deserializes value from json. It uses `jsonDeserialize` method of StdLib native contract. It performs deserialization as follows: strings -> []byte (string) from base64 integers -> (u)int* types null -> interface{}(nil) arrays -> []interface{} maps -> map[string]interface{}
func JSONSerialize ¶
func JSONSerialize(item interface{}) []byte
JSONSerialize serializes value to json. It uses `jsonSerialize` method of StdLib native contract. Serialization format is the following: []byte -> base64 string bool -> json boolean nil -> Null string -> base64 encoded sequence of underlying bytes (u)int* -> integer, only value in -2^53..2^53 are allowed []interface{} -> json array map[type1]type2 -> json object with string keys marshaled as strings (not base64).
func Serialize ¶
func Serialize(item interface{}) []byte
Serialize calls `serialize` method of StdLib native contract and serializes any given item into a byte slice. It works for all regular VM types (not ones from interop package) and allows to save them in storage or pass into Notify and then Deserialize them on the next run or in the external event receiver.
