If it's the same librsvg as below, then it looks like it has an 
API function which can also load a SVG from memory:

https://developer.gnome.org/rsvg/2.40/RsvgHandle.html#rsvg-handle-new-from-data

To answer your original question, I think the best way to do this 
is to create a pipe on the filesystem. Once created, you can feed 
data through it without touching the disk.
