clasp-core

Core types and encoding for the CLASP (Creative Low-Latency Application Streaming Protocol).

Features

• Message Types: Set, Publish, Subscribe, Bundle, Snapshot, etc.
• Value Types: Int, Float, Bool, String, Bytes, Array, Map, Null
• Binary Encoding (v3): 55% smaller, 4x faster than JSON/MessagePack
• Address Patterns: Hierarchical addressing with wildcards (*, **)
• Signal Types: Param, Event, Stream, Gesture, Timeline

Usage

use clasp_core::{Message, SetMessage, Value, codec};

// Create a set message
let msg = Message::Set(SetMessage {
    address: "/lights/front/brightness".to_string(),
    value: Value::Float(0.75),
    revision: None,
    lock: false,
    unlock: false,
});

// Encode to v3 binary format
let encoded = codec::encode(&msg).unwrap();

// Decode (auto-detects v2/v3)
let (decoded, _frame) = codec::decode(&encoded).unwrap();

Binary Encoding

CLASP binary encoding is 55% smaller and 4-7x faster than JSON/MessagePack:

Address Patterns

CLASP uses hierarchical addresses with wildcard support:
