SCALE Serialization

scales - SCALE Serialization

Making use of type information this library allows conversion to/from SCALE encoded data, specially useful when conversion is for dynamic types like JSON.

From SCALE

scales::Value wraps the raw SCALE binary data and the type id within type registry giving you an object that can be serialized to any compatible format.

let value = scales::Value::new(scale_binary_data, type_id, &type_registry);
serde_json::to_string(value)?;

To SCALE

Public methods from the scales::serializer::* module(feature experimental-serializer) allow for a best effort conversion of dynamic types(e.g. serde_json::Value) to SCALE binary format. The serializer tries to be smart when interpreting the input and convert it to the desired format dictated by the provided type in the registry.

// simple conversion
let scale_data = to_vec(some_serializable_input); // or to_bytes(&mut bytes, input);

// with type info
let scale_data = to_vec_with_info(input, Some((&registry, type_id)));

// from an unordered list of properties that make an object
let input = vec![("prop_b", 123), ("prop_a", 456)];
let scale_data = to_vec_from_iter(input, (&registry, type_id));
