weida 0.1.0-alpha.2

//! weida: a QUIC-native messaging framework.
//!
//! This crate hosts the runtime, the native QUIC transport, the raw stream core
//! and the brokerless messaging patterns: Req/Rep, Push/Pull, Pub/Sub, PAIR,
//! SURVEY and BUS — the whole nanomsg set, none of which adds wire
//! vocabulary. A completion is a **cursor**: a level plus an absolute byte
//! offset, reported on a unidirectional stream of its own
//! ([`Cursors`], [`Reporter`]).
//! `docs/ARCHITECTURE.md` describes the layer model,
//! `docs/PROTOCOL.md` is the normative wire specification, and
//! `docs/FAILURE_MODEL.md` defines what each outcome means.
//!
//! ```no_run
//! use weida::{Runtime, RuntimeConfig, TransferMeta, Trust};
//!
//! # async fn example() -> weida::Result<()> {
//! let runtime = Runtime::new(RuntimeConfig::default())?;
//!
//! // Trust belongs to the dialling endpoint, not to the runtime. Here the
//! // address itself names the peer's public key, so nothing else is needed.
//! let requester = runtime.requester(Trust::by_address());
//! requester
//!     .connect("weida://sha256:9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08@127.0.0.1:7443/transform")
//!     .await?;
//!
//! // One bidirectional stream: the request half and the reply half. The
//! // stream is the correlation, so nothing on the wire names the exchange.
//! let (mut transfer, reply) = requester.open(TransferMeta::default()).await?;
//! transfer.write_all(b"hello weida").await?;
//! transfer.finish()?;
//!
//! let body = reply.recv().await?.collect(64 * 1024).await?;
//! println!("{}", String::from_utf8_lossy(&body));
//! # Ok(())
//! # }
//! ```
//!
//! The example above runs on the caller's ambient Tokio reactor. A caller
//! that has none — or whose executor is not Tokio at all — uses
//! [`Runtime::owned`] instead: the runtime then owns the reactor `quinn`
//! needs, and every task, timer and name lookup weida performs runs there,
//! while the futures it hands back may be driven by any executor. Transfer
//! payloads implement both the `tokio::io` and the `futures-io` traits for
//! the same reason.
