VTable of function pointers for app operations. Returned by the _node_app_entry symbol.

Fields

metadata: NodeAppMetadata

App metadata

init: unsafe extern "C" fn(ctx: *const c_void) -> FfiResult

Initialize the app with the host context. Called once after loading. Returns FfiResult.

shutdown: unsafe extern "C" fn() -> FfiResult

Shut down the app gracefully. Called before unloading the shared library.

handle_request: unsafe extern "C" fn(request_json: *const u8, request_len: usize) -> FfiResult

Handle an HTTP request. request_json is a pointer to UTF-8 JSON bytes of length request_len. Returns FfiResult with response JSON in data/data_len.

handle_event: unsafe extern "C" fn(event_json: *const u8, event_len: usize) -> FfiResult

Handle a domain event. event_json is a pointer to UTF-8 JSON bytes of length event_len. Returns FfiResult (data is typically empty for events).

handle_capability: unsafe extern "C" fn(request_json: *const u8, request_len: usize) -> FfiResult

Handle a capability invocation from the capability router. request_json is a pointer to UTF-8 JSON bytes (CapabilityRequest) of length request_len. Returns FfiResult with CapabilityResponse JSON in data/data_len. Response is limited to 16MB.

free: unsafe extern "C" fn(ptr: *mut u8, len: usize)

Free memory allocated by the app (for response data). The host calls this to release FfiResult.data.
