Enum LoopbackRelease 

pub enum LoopbackRelease {
    Released,
    AlreadyAbsent,
    PrivilegeUnavailable(String),
    Failed(String),
}

Outcome of attempting to release a loopback alias.

A caller cannot treat every non-removal the same way: one where the helper is missing or sudo needs a password will not resolve itself by retrying, so it must be surfaced once and recorded as unsatisfiable here, rather than kept as a cleanup that is retried forever.

Variants

Released

The alias was configured and has been removed.

AlreadyAbsent

Nothing was configured for this address; there was nothing to remove.

PrivilegeUnavailable(String)

The alias is still configured, but this process cannot escalate the privileges removal needs right now (helper unavailable, sudo -n needs a password). Retrying without a privilege change will not help.

Failed(String)

The alias is still configured and removal failed for a reason a later attempt might resolve.
