crates.io | API docs

What it does

moqtap-client is a full MoQT endpoint that can subscribe, publish, fetch, and discover — all on a single QUIC connection.

Usage

use moqtap_client::MoqEndpoint;

let endpoint = MoqEndpoint::connect(
    "https://relay.example.com/moq",
    TlsConfig::AcceptAny,
    DraftVersion::Draft14,
).await?;

// Subscribe to a track
let sub = endpoint.subscribe(
    &["chat"],
    "messages",
    Filter::LatestObject,
).await?;

// Receive objects
while let Some(object) = sub.recv().await {
    println!("Object: group={} id={} size={}",
        object.group_id, object.object_id, object.payload.len());
}

Capabilities

• Subscribe — with filter types, priority, group order
• Fetch — retrieve historical objects by range
• Discover — namespace discovery via SUBSCRIBE_NAMESPACE
• Track status — query track availability
• Publish — send objects (structurally present, full UI in v0.2+)

Request ID management

The client uses even request IDs starting at 0, incrementing by 2. The relay uses odd IDs. This is per the MoQT spec.
