osc-ir

⚠️ EXPERIMENTAL ⚠️
This crate is experimental and APIs may change significantly between versions.

A protocol-agnostic Intermediate Representation (IR) for OSC-adjacent data structures, designed to work seamlessly with JSON, MessagePack, and other serialization formats.

Features

• OSC Version Support: Configurable OSC 1.0 and OSC 1.1 support via feature flags
• no_std Compatible: Core functionality works without std (requires alloc feature for owned containers)
• Bundle Support: Full OSC Bundle implementation with nested bundle support
• Flexible Types: Support for all OSC types including timestamps, binary data, and extensible types
• Serde Integration: Optional serde support for JSON/MessagePack serialization

Usage

Add this to your Cargo.toml:

[dependencies]
osc-ir = "0.1.0-alpha.1"

Basic Example

use osc_ir::{IrValue, IrBundle, IrTimetag};

// Create basic values
let message = IrValue::from("hello world");
let number = IrValue::from(42);
let boolean = IrValue::from(true);

// Create arrays
let array = IrValue::from(vec![
    IrValue::from(1),
    IrValue::from(2), 
    IrValue::from(3)
]);

// Create bundles with timetags
let mut bundle = IrBundle::new(IrTimetag::from_ntp(12345));
bundle.add_message(message);
bundle.add_message(number);

let bundle_value = IrValue::Bundle(bundle);

OSC 1.1 Features

Enable OSC 1.1 support for additional types:

[dependencies]
osc-ir = { version = "0.1.0-alpha.1", features = ["osc11"] }

use osc_ir::IrValue;

// OSC 1.1 Color type (RGBA)
let color = IrValue::color(255, 128, 0, 255);

// OSC 1.1 MIDI message
let midi = IrValue::midi(0, 0x90, 60, 127);

Serde Support

For JSON/MessagePack serialization:

[dependencies]
osc-ir = { version = "0.1.0-alpha.1", features = ["serde"] }

Feature Flags

• alloc (default): Enable owned containers (Vec, String, etc.) for no_std environments
• serde: Enable serde serialization support
• osc10 (default): OSC 1.0 support (bundles, timetags, basic types)
• osc11: OSC 1.1 support (includes OSC 1.0 plus Color and MIDI types)

no_std Support

The crate works in no_std environments with the alloc feature:

[dependencies]
osc-ir = { version = "0.1.0-alpha.1", default-features = false, features = ["alloc"] }
