⚠️ Breaking Changes

• iroh

  • removed

    • iroh::endpoint::Builder:: tls_x509 removed, this is the tls mechanism that has been removed
    • iroh::endpoint::Builder:: tls_raw_public_keys  removed, this is the default mechanism now, so not needed anymore
    • Display implementation was removed for SecretKey, use .to_bytes() and encode as hex to get the previous bytes explicitly, for example:

    rust let encoded_key = data_encoding::HEXLOWER.encode(&secret_key.to_bytes())

    • removed iroh_relay::protos::stun::StunError
    • removed iroh_relay::server::testing::stun_config
    • removed iroh_relay::protos::stun
    • removed iroh_relay::quic::QuicClient::get_addr_and_latency
    • removed DEFAULT_STUN_PORT
    • Removed iroh::discovery::dns::DnsDiscovery::new, use DnsDiscovery::builder instead
    • Removed iroh::discovery::pkarr::PkarrPublisher::new, use PkarrPublisher::builder instead
    • Removed iroh::discovery::pkarr::PkarrPublisher::with_options, use PkarrPublisher::builder instead
    • Removed iroh::discovery::pkarr::PkarrResolver::new, use PkarrResolver::builder instead
      • changed
    • all public APIs return concrete error types, rather than anyhow::Error
    • iroh::protocol::ProtocolHandler methods now return impl Future instead of BoxFuture. You can simply remove the Box::pin(async move {}) from the implementations and instead implement the methods as async fn. See the updated documentation for the iroh::protocol module for an example.
    • iroh::protocol::ProtocolHandler is no longer dyn-compatible. If you need a dyn-compatible version, you need to build your own dyn-compatible wrapper trait. See the (non-public) DynProtocolHandler in iroh::protocol as an example.
    • iroh::watcher is now its own crate n0-watcher, but the Watcher trait is still a top level export in iroh
    • iroh::endpoint::Endpoint::node_addr now returns impl Watcher<Value = Option<NodeAddr>>
    • iroh::endpoint::Endpoint::home_relay now returns impl Watcher<Value = Vec<RelayUrl>>
    • iroh::endpoint::Endpoint::bound_sockets now returns Vec<SocketAddr>
    • iroh-quinn is updated to 0.14.0
    • iroh::protocol::RouterBuilder::accept now takes impl Into<Box<dyn DynProtocolHandler>> instead of impl ProtocolHandler. Because of a blanket From impl this change does not need any changes by users: you can still pass any impl ProtocolHandler to accept. Additionally, if you have your own builder struct upstream, you can now also pass a Box<dyn DynProtocolHandler> to accept, which wasn't possible previously.
    • iroh::discovery::Lagged changed from a tuple to a struct
    • iroh::watcher::Disconnected is changed from a tuple to a struct
    • iroh::watcher::Disconnected is no longer UnwindSafe or RefUnwindSafe
    • iroh::watcher::InitializedFut is no longer RefUnwindSafeiroh-base
    • iroh::endpoint::Builder::add_discovery now takes an impl iroh::discovery::IntoDiscovery argument instead of a closure that returns a Discovery. You can implement that on a builder struct, and any T: Discovery has an auto-impl of IntoDiscovery.
    • iroh::discovery::Discovery::resolve no longer gets a &Endpoint argument. If you need an endpoint in your discovery service, add a builder struct and implement IntoDiscovery for it, which gives you an endpoint that you can clone into your service
    • iroh::discovery::pkarr::PkarrPublisher::n0_dns now takes no arguments and returns a PkarrPublisherBuilder. The secret key is set on PkarrPublisherBuilder::build instead.

• iroh-base

  • changed
    • iroh_base::ticket::Error is renamed to iroh_base::ticket::ParseError
    • iroh_base::key::KeyParsingError has changed from a thiserror error to a snafu erroriroh-relay
• iroh-relay
  • changed
    • iroh_relay::node_info::MaxLengthExceededError is no longer UnwindSafe or RefUnwindSafe
    • iroh_relay::node_info::MaxLengthExceededError was changed from a thiserror to a snafu error
    • iroh_relay::client::ConnSendError is now iroh_relay::client::SendError
    • iroh_relay::protos::stun::Error is now iroh_relay::protos::stun::StunError
