pub struct FilterOutputStream { /* private fields */ }
Expand description
Base class for output stream implementations that perform some kind of filtering operation on a base stream. Typical examples of filtering operations are character set conversion, compression and byte order flipping.
This is an Abstract Base Class, you cannot instantiate it.
§Properties
§base-stream
Readable | Writeable | Construct Only
§close-base-stream

Requests an asynchronous close of the stream, releasing resources
related to it. When the operation is finished @callback will be
called. You can then call g_output_stream_close_finish() to get
the result of the operation. Read more

&self,
cancellable: Option<&impl IsA<Cancellable>>,
) -> Result<(), Error>
fn flush( &self, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<(), Error>
Forces a write of all user-space buffered data for the given
@self. Will block during the operation. Closing the stream will
implicitly cause a flush. Read more

fn is_closing(&self) -> bool
Checks if an output stream is being closed. This can be

the closing 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
