spate-core 0.1.0

Engine for the Spate framework: records, operator chains, source/sink abstractions, checkpointing, backpressure, config, metrics, and the pipeline runtime. Applications should depend on the `spate` facade crate instead.
Documentation
//! The engine of the Spate framework.
//!
//! `spate-core` contains the pipeline runtime and every technology-neutral
//! abstraction: records and their checkpoint tokens, the operator chain,
//! the source and sink traits, checkpointing, backpressure, configuration
//! loading, metrics, and the admin server.
//!
//! Applications should depend on the [`spate`](https://crates.io/crates/spate)
//! facade crate rather than on `spate-core` directly.
//!
//! The architecture and its invariants are documented in `docs/DESIGN.md`;
//! the metric taxonomy in `docs/METRICS.md`.

// tokio's own sources change shape under `--cfg loom` (net disappears), so
// anything touching tokio::net is compiled out of loom model builds.
#[cfg(not(loom))]

/// Re-export of the [`bytes`] crate: [`RowEncoder`](sink::RowEncoder)
/// signatures take [`bytes::BytesMut`], so connector authors can use this
/// re-export instead of declaring their own `bytes` dependency (declaring
/// one is also fine — versions are compatible per the workspace pin).
