fn read_bytes( &self, count: usize, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<Bytes, Error>
Like g_input_stream_read(), this tries to read @count bytes from
the stream in a blocking fashion. However, rather than reading into
a user-supplied buffer, this will create a new #GBytes containing
the data that was read. This may be easier to use from language
bindings. Read more

Limits the lifetime of
closure
to the lifetime of the object. When
the object’s reference count drops to zero, the closure will be
invalidated. An invalidated closure will ignore any calls to
invoke_with_values
, or
invoke
when using Rust closures.source§fn emit<R>(&self, signal_id: SignalId, args: &[&dyn ToValue]) -> Rwhere
