inputx-wubi-data

Embedded Wubi 86 IDFv1 dict blob + IdfReader OnceLock + Layer-from- EntryFlags helper for the inputx-wubi engine, packaged as a publishable stone.

[dependencies]
inputx-wubi-data = "1.6"

Successor to inputx-wubi-cement under the v1.5 D11 taxonomy correction (2026-05): cement = application source code, not a published crate. The historical -cement-suffix crate is deprecated and re-exports from this crate for backward compatibility.

What's in the box

EMBEDDED_WUBI_IDF — IDFv1 binary dict blob (~4.4 MB, 135,822 entries). Each entry's EntryFlags::engine_tag() carries the wubi Layer enum index (v1.4.7 sub-phase A4 step 2 schema bump), so cement-side fills can reconstruct (word, layer, raw_freq) without re-reading the inputx_wubi::WubiDict table.
wubi_idf_reader() — process-global OnceLock<IdfReader>; the 4 MB parse + sha256 verify amortizes once across the process, subsequent lookup(code) calls are O(|code|) FST walks with zero per-query allocation.
layer_from_idf_tag(u8) -> inputx_wubi::Layer — reverse of Layer::as_u8; falls back to Layer::Auto on out-of-range bytes.
Table helpers (lookup, lookup_with_scores, lookup_with_layer, lookup_with_freq_layer, prefix_predictions, record_pick) — process-global stateful WubiDict cache + per-code lookups, with rare-CJK filter (set_show_rare / show_rare).
L0 helpers (export_l0, import_l0) + warmup + the inputx_wubi::L0Snapshot re-export.

What's NOT here

Stateful WubiEngine (buffer / handle_letter / AutoCommitPolicy / commit_index / L0 pin state machine) — per the v1.5 D11 correction, that classifies as application cement (your own wubi.rs / engine.rs). The Inputx monorepo's reference implementation lives at inputx-core/src/wubi/engine.rs (370 LOC, MIT/Apache-2.0; copy into your app).

Usage

use inputx_wubi_data::{wubi_idf_reader, layer_from_idf_tag};

let r = wubi_idf_reader();
for entry in r.lookup(b"g") {
    let layer = layer_from_idf_tag(entry.flags.engine_tag());
    println!("{} layer={layer:?} raw_freq={}", entry.word, entry.raw_freq);
}
// 一 layer=Jianma1 raw_freq=N

API stability

EMBEDDED_WUBI_IDF byte slice — stable module path across 1.x; underlying bytes rebuild with each release as the upstream wubi data refreshes.
wubi_idf_reader / layer_from_idf_tag / table helpers — signatures stable across 1.x.
