Rust Crates

moqtap’s protocol core is a set of MIT-licensed Rust crates published to crates.io. Use them in your own projects.

Crate	Description	crates.io	API Docs
moqtap-codec	Zero-dependency wire codec for drafts 07–17	crates.io	rustdoc
moqtap-client	Outbound QUIC/WebTransport MoQT client	crates.io	rustdoc
moqtap-proxy	Transparent intercepting proxy	crates.io	rustdoc
moqtap-trace	.moqtrace binary format reader/writer	crates.io	rustdoc

Quick start

Add a crate to your Cargo.toml:

[dependencies]
moqtap-codec = "0.1"
moqtap-client = "0.1"

Each supported draft is a separate Cargo feature (draft07..draft17) on both moqtap-codec and moqtap-client. The codec defaults to all-drafts; the client defaults to draft14. Enable additional drafts to negotiate them at runtime.

Dependency graph

moqtap-codec          Pure codec, no I/O. Foundation for everything.
    │
    ├── moqtap-client     Outbound QUIC client, endpoint logic, session management.
    │
    ├── moqtap-proxy      Intercepting proxy (depends on codec + client transport).
    │
    └── moqtap-trace      Event capture, .moqtrace file format.

Use only what you need — moqtap-codec alone is useful if you just want to parse MoQT messages without any I/O, and moqtap-trace can be embedded into a relay or custom client to emit .moqtrace files.

Minimum supported Rust version

Rust 1.83 or later.
