supportsAsyncMultiResultStream property
True when the loaded native library exports
odbc_transaction_begin_v2 (added in Sprint 4.1). Callers that need
the accessMode (READ ONLY / READ WRITE) parameter should gate
on this flag; older binaries silently fall back to v1, which is
equivalent to always passing accessMode = readWrite.
Implementation
bool get supportsAsyncMultiResultStream =>
_odbc_stream_multi_start_async_ptr != null &&
_odbc_stream_poll_async_ptr != null;
