Provided Methods§
fn write( &self, buffer: &[u8], cancellable: Option<&Cancellable> ) -> Result<usize, Error>
fn close(&self, cancellable: Option<&Cancellable>) -> Result<(), Error>
sourcefn flush(&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
sourcefn splice(
&self,
input_stream: &InputStream,
flags: OutputStreamSpliceFlags,
cancellable: Option<&Cancellable>
) -> Result<usize, 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 InputStream
.
flags
a set of OutputStreamSpliceFlags
.
cancellable
optional Cancellable
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.
