fn flush_async<P: FnOnce(Result<(), Error>) + 'static>( &self, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )
Forces an asynchronous write of all user-space buffered data for

fn is_closing(&self) -> bool
Checks if an output stream is being closed. This can be
used inside e.g. a flush implementation to see if the
flush (or other i/o operation) is called from within
the closing operation. Read more

Splices a stream asynchronously.
When the operation is finished @callback will be called.
You can then call g_output_stream_splice_finish() to get the
result of the operation. Read more

fn write_bytes( &self, bytes: &Bytes, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<isize, Error>
A wrapper function for g_output_stream_write() which takes a
#GBytes as input. This can be more convenient for use by language
bindings or in other cases where the refcounted nature of #GBytes
is helpful over a bare pointer interface. Read more

fn write_bytes_async<P: FnOnce(Result<isize, Error>) + 'static>( &self, bytes: &Bytes, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )
This function is similar to g_output_stream_write_async(), but
takes a #GBytes as input. Due to the refcounted nature of #GBytes,
this allows the stream to avoid taking a copy of the data. Read more
