5/// Trait for node manager builders. Node managers are built at the same time as the server,
6/// after it has been configured, so each custom node manager needs to defined a builder type
7/// that implements this trait.
8///
9/// Build is infallible, if you need anything to fail, you need to either panic or
10/// propagate that failure to the user when creating the builder.
