Module surfman::platform::generic::multi

An abstraction that allows the choice of backends dynamically.

This is useful on Unix systems, because it allows for Wayland to be tried first, and, failing that, to use X11.

Each type here has two type parameters: a “default” device and an “alternate” device. Opening a connection will first attempt to open the default connection and, if that fails, attempts to open the alternate connection. You can also create instances of these types manually (i.e. wrapping a default or alternate type directly) if you have platform-specific initialization code.

You can “daisy chain” these types to switch between more than two backends. For example, you might use multi::Device<wayland::Device, multi::Device<x11::Device, osmesa::Device>> for a device that can dynamically switch between Wayland, X11, and OSMesa.
