Provided Methods

fn write( &self, buffer: &[u8], cancellable: Option<&Cancellable>, ) -> Result<usize, Error>

fn close(&self, cancellable: Option<&Cancellable>) -> Result<(), Error>

fn flush(&self, cancellable: Option<&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.

This function is optional for inherited classes.

If @cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional cancellable object

Returns

true on success, false on error

fn splice( &self, input_stream: &InputStream, flags: OutputStreamSpliceFlags, cancellable: Option<&Cancellable>, ) -> Result<usize, Error>

Splices an input stream into an output stream.

source

a #GInputStream.

flags

a set of #GOutputStreamSpliceFlags.

cancellable

optional #GCancellable object, None to ignore.

Returns

a #gssize containing the size of the data spliced, or -1 if an error occurred. Note that if the number of bytes spliced is greater than G_MAXSSIZE, then that will be returned, and there is no way to determine the actual number of bytes spliced.

Object Safety

This trait is not object safe.
