Function init_network 

pub fn init_network()

Initialize the FoundationDB network.

This function is safe to call multiple times - only the first call will actually initialize the network, subsequent calls return immediately.

The FoundationDB network can be booted once per process and can never be restarted: after shutdown_network(), any subsequent call to this function panics.

Before the process exits, drop all Database and transaction handles and then call shutdown_network(). Skipping the shutdown can segfault the FoundationDB client during teardown; calling it while a handle is still alive can instead block on the network thread join.
