This method is only available on UNIX.

When designing D-Bus APIs that are intended to be interoperable, please note that non-GDBus implementations of D-Bus can usually only access file descriptors if they are referenced by a value of type G_VARIANT_TYPE_HANDLE in the body of the message.

A UnixFDList or None.

source

pub fn to_blob( &self, capabilities: DBusCapabilityFlags ) -> Result<Vec<u8>, Error>
