(FIDIUS-I-0026, design decision D2). hash FNV-1a interface hashing for compile-time ABI drift detection. package Source package manifest types and parsing. python_descriptor Compile-time descriptor of a fidius interface used by the Python loader. registry Plugin registry assembly for multi-plugin dylibs. sockets Capability-gated outbound TCP for sandboxed WASM connectors (FIDIUS-I-0033).
Portable (backed by std::net → wasi:sockets), so present in host builds too.
Capability-gated outbound TCP for sandboxed WASM connectors (FIDIUS-I-0033) —
the raw-wire counterpart of [http], for DB/warehouse drivers. Backed by
std::net::TcpStream (which is wasi:sockets on wasm32-wasip2), so it is
portable: present on the host too (a normal socket), no cfg(wasm) gate.
fidius::sockets — capability-gated outbound TCP for sandboxed WASM
connectors (FIDIUS-I-0033). status FFI status codes returned by plugin method shims. stream_ffi cdylib server-streaming FFI handle (FIDIUS-I-0026 Phase 3 / CS.1, T-0138). stream_marker The fidius::Stream<T> server-streaming return marker (FIDIUS-I-0026, D4). value Value — a neutral, self-describing value tree for the plugin boundary.wasm_descriptor Compile-time descriptor of a fidius interface used by the WASM loader. wire Wire format serialization for Fidius plugin FFI boundary. fidius_plugin_registry Emit the fidius_get_registry export function. DescriptorPtr A Sync wrapper for a raw pointer to a PluginDescriptor. MetaKv Static key/value pair for method-level or trait-level metadata. MethodMetaEntry Per-method metadata entry. One entry per method in declaration order,
stored in the array referenced by PluginDescriptor::method_metadata. PluginDescriptor Metadata descriptor for a single plugin within a dylib. PluginError Error returned by plugin method implementations to signal business logic failures. PluginRegistry Top-level registry exported by every Fidius plugin dylib. Stream Marker type a plugin interface uses to declare a server-streaming method: ValueError Error produced while converting to or from Value BufferStrategyKind Buffer management strategy for an interface. Value A self-describing value crossing the plugin-call boundary. ABI_VERSION Current version of the PluginDescriptor struct layout. Derived from the
fidius-core crate version per ADR-0002. FIDIUS_MAGIC Magic bytes identifying a Fidius plugin registry. REGISTRY_VERSION Current version of the PluginRegistry struct layout. STATUS_BUFFER_TOO_SMALL Output buffer was too small (CallerAllocated/Arena strategies only).
The out_len parameter contains the required size. Retry with a larger buffer. STATUS_OK Method executed successfully. Output buffer contains the serialized result. STATUS_PANIC A panic was caught at the extern "C" boundary via catch_unwind.
The output buffer may contain a panic message string, but this is not guaranteed. STATUS_PLUGIN_ERROR The plugin method returned an error. The output buffer contains a
serialized PluginError with details. STATUS_SERIALIZATION_ERROR Serialization or deserialization failed at the FFI boundary.
This indicates a bug in the generated shims or a type mismatch. STATUS_STREAM_END Clean end of a server-stream: the streaming next() shim has no more items
(FIDIUS-I-0026 / FIDIUS-T-0138). Distinct from STATUS_OK with out_len == 0,
which is a real zero-byte item (e.g. a unit () item). from_value Convert a ValueDeserialize to_value Convert any SerializeValue
