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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
