Purpose

Peer discovery, mutable records, DID envelopes, local relay sessions, adapter registry, record stores, and handles. This page follows the real source shape for Weave Dht and explains the workflow a developer is likely to use first.

​
Network contract

Document peer identity, topic selection, message framing, session lifetime, retry behavior, metrics, and what must be stable between releases. Any change here can strand peers, so examples should be exercised with at least two real processes.

​
Primary types to know

  • AdapterRegistry — network/weave-dht/src/methods.rs
  • AnnouncementState — network/weave-dht/src/weave.rs
  • AnnounceOpts — network/weave-dht/src/weave.rs
  • DhtClient — network/weave-dht/src/lib.rs
  • DhtConfig — network/weave-dht/src/lib.rs
  • DhtHandle — network/weave-dht/src/lib.rs
  • DhtMethodAdapter — network/weave-dht/src/methods.rs
  • DhtNode — network/weave-dht/src/lib.rs
  • DhtNodeBuilder — network/weave-dht/src/lib.rs
  • DidEnvelope — network/weave-dht/src/envelope.rs
  • EnhancedDhtNode — network/weave-dht/src/enhanced.rs
  • MarsAdapter — network/weave-dht/src/methods.rs

​
Example shape

use weave_dht::*;

// Minimal example skeleton. Replace placeholders with the concrete constructor
// listed on the API Surface page for this library.
async fn example() -> Result<(), Box<dyn std::error::Error>> {
    // 1. Build config or open storage.
    // 2. Execute one operation from this page.
    // 3. Assert the observable result before wiring peers or persistence.
    Ok(())
}

​
Release-quality documentation checklist

  • Every public type on the API Surface page has at least one sentence of behavior documentation.
  • Every fallible operation lists errors and recovery guidance.
  • Every networked example names the peer/session/topic lifecycle.
  • Every storage example names durability, repair, and deletion semantics.
