Enum HostStatus 

pub enum HostStatus {
    Unknown,
    Down,
    Filtered,
    Up,
}

The high-level reachability state of a network host.

Variants are ordered by semantic severity and reachability certainty: Unknown < Down < Filtered < Up.

This ordering is critical for the Host::merge logic: if one scan identifies a host as Down but a concurrent high-fidelity scan identifies it as Up, the Up status will prevail.

Variants

Unknown

Reachability has not yet been determined or the scan results were inconclusive.

Down

The host is explicitly confirmed to be offline or unreachable (e.g., ICMP Host Unreachable).

Filtered

The host exists on the network, but active probes are being dropped or rejected by a firewall.

Up

The host is confirmed to be online and fully responding to probes.

Implementations

impl HostStatus

pub fn is_up(&self) -> bool

Returns true if the host is confirmed to be fully online and responding.

pub fn is_down(&self) -> bool

Returns true if the host is explicitly confirmed to be offline.

pub fn is_alive(&self) -> bool

Returns true if there is evidence the host is present on the network, even if communication is restricted by a firewall.
