Enum ProbeRegistration 

pub enum ProbeRegistration {
    Success,
    Failed(String),
}

ProbeRegistration stores the result of registering probes with the DTrace kernel module.

Though unlikely, it’s possible that probe registration fails. This may happen, for example, if the DTrace kernel module is extremely low on memory. One may want to abort the application in this case, or one might decide that a running but degraded application is better than nothing i such a situation. The ProbeRegistration enum contains information about whether probes were successfully registered. The caller may decide how to handle such a case.
