exportTraceToString method

int exportTraceToString(String input)

Exports trace data to an output buffer (native behavior dependent).

Implementation

int exportTraceToString(String input) {
  if (!_initialized) {
    throw Exception('Not initialized');
  }
  if (!_symbolsAvailable) {
    return -1;
  }

  final encoded = utf8.encode(input);
  final len = encoded.isEmpty ? 1 : encoded.length;
  final out = malloc<ffi.Uint8>(len);
  try {
    if (encoded.isNotEmpty) {
      out.asTypedList(len).setAll(0, encoded);
    } else {
      out.value = 0;
    }
    final result = _otelExportTraceToStringPtr!
        .asFunction<int Function(ffi.Pointer<ffi.Uint8>, int)>()(
      out,
      len,
    );
    if (result != 0) {
      _captureNativeError();
    }
    return _legacySuccessCode(result);
  } finally {
    malloc.free(out);
  }
}
