This would be provider specific.  I'm not aware of anything that's coded to handle failures.

Having an example of this over libfabric would be great, though I'm not sure who's going to volunteer to write this.

It's not clear to me how fault tolerance relates to a networking API.  For example, what specific lower-level features does an app need to make this happen?  Are their restrictions that providers need to report to apps regarding their level of support?  Is this something that even belongs to this level of API?
