C29 compile/unit seam, core carrier (iteration 1 of the self-description
spec): DocGateFault { Empty, RestatesName } + doc_gate() — deterministic
string-shape check, never content judgement — and NodeSchema gains the
required pub doc: &'static str, so every construction site must declare
a meaning line (compiler-enumerated). Core's own 10 test literals thread
doc: "test-only schema"; doc_gate/DocGateFault re-exported at crate root.
Downstream crates are E0063-broken by design until their sites thread
the field (tasks 3-7 of the plan); gates here are crate-scoped:
cargo test -p aura-core (59 green) + clippy -p aura-core (clean).
Interim subset commit of the implement run after adjudicating a
cross-task discard: task 2's file checkout had destroyed task 1's
node.rs/lib.rs work; restored from the loop's recovery snapshot
53c55c3 and merged with task 2's field threading.

//! `aura-core` — the shared contract every aura component links against.
|
|
//!
|
|
//! This crate is the boundary forced by the cdylib hot-reload model: both the
|
|
//! engine and every hot-reloadable node cdylib depend on it, so it stays small
|
|
//! and stable.
|
|
//!
|
|
//! Delivered so far (cycle 0001 — the streaming substrate):
|
|
//!
|
|
//! - the four scalar base types streamed as SoA: [`Scalar`] / [`ScalarKind`] /
|
|
//! [`Timestamp`] (C7);
|
|
//! - [`Column`] — a fixed-capacity, bounded-lookback ring with financial
|
|
//! indexing (index 0 = newest) and a `run_count` freshness primitive (C5/C8),
|
|
//! read zero-copy through a [`Window`];
|
|
//! - [`AnyColumn`] — the type-erased edge over the four column kinds, with an
|
|
//! edge-time kind check ([`KindMismatch`]) (C7).
|
|
//!
|
|
//! Delivered in cycle 0002 — the node contract:
|
|
//!
|
|
//! - [`Node`] — the `lookbacks`/`eval` contract every node implements (C8); the
|
|
//! static signature ([`NodeSchema`] / [`PortSpec`] declaring input ports by kind
|
|
//! and the output record of [`FieldSpec`] columns; length 1 = scalar) is declared
|
|
//! on the node's [`PrimitiveBuilder`], pre-build;
|
|
//! - [`Ctx`] — the per-`eval` read-side: zero-copy, financial-indexed [`Window`]
|
|
//! access into each input (closing the cycle-0001 read-side gap on
|
|
//! [`AnyColumn`]).
|
|
//!
|
|
//! Still to come (subsequent cycles): the broker-independent
|
|
//! position-event output and downstream broker nodes (C10), and the run registry
|
|
//! (C18/C22).
