Crate jmdict_fast_ffi 

FFI-agnostic facade over jmdict-fast.

This crate intentionally exposes only the shapes that every popular Rust FFI generator can describe: owned data, concrete enums, Arc<Self> handles, no lifetimes, no generics, no iterators across the boundary. The generator crates (jmdict-fast-uniffi, jmdict-fast-frb, jmdict-fast-bolt, …) describe these types externally (UDL, FRB scan, bolt IDL) and add their own scaffolding — they should not need to reach into jmdict-fast itself.

Differences from jmdict-fast

• Dict::load / load_default return Arc<Self> (every generator requires Arc for object handles).
• The chainable QueryBuilder collapses into a QueryOptions record so callers in foreign languages don’t need fluent chaining.
• JmdictError::IoError(std::io::Error) collapses into Error::Io { message } so the error survives codegen — io::Error is not FFI-safe.
• Iterators (iter_entries) become an explicit (start, count) pagination.

Re-exports

Data types (Entry, KanjiEntry, Xref, …) are re-exported unchanged from jmdict-fast. They are already plain POD with public fields and no lifetimes — every FFI generator can describe them as records.

Structs

BatchResult

Per-term batch result, paired with the original term so callers can correlate output without relying on input order.

DataVersion

Dictionary data version information.

DeinflectionInfo

Information about how a term was deinflected to find its base form.

Dict

FFI-friendly handle around a loaded dictionary. Construct via Dict::load or Dict::load_default; the resulting Arc<Dict> can be shared freely across threads and FFI calls.

Entry

GlossEntry

KanaEntry

KanjiEntry

LanguageSource

LookupResult

A single dictionary lookup hit.

QueryOptions

Options for Dict::lookup_with_options / Dict::lookup_batch.

SenseEntry

Xref

Enums

Error

Errors surfaced across the FFI boundary.

MatchMode

The search mode for a query.

MatchType

How a lookup result matched the query term.
