Enum NotFollowed 

pub enum NotFollowed {
    Unresolved,
    Unspecified,
    Broadcast,
    DirectedBroadcast,
    Multicast,
    Loopback,
    Own,
}

Why a BDT entry was not followed: its address is no BBMD a read may go to.

Variants

Unresolved

All zeros: a BBMD reports an entry configured by a host name it couldn’t resolve this way (Annex J.4.4.1).

Unspecified

An unspecified address or port 0.

Broadcast

The limited broadcast address.

DirectedBroadcast

A subnet’s directed broadcast address: a BDT entry always holds a BBMD’s own unicast address, so one that is the local broadcast address, or has every host bit of its own mask set, is none.

Multicast

A multicast address.

Loopback

A loopback address, while this node isn’t on loopback itself.

Own

This node’s own address.

Implementations

impl NotFollowed

pub fn as_str(self) -> &'static str

The reason as a kebab-case word.

pub fn check(row: &BdtRow, here: &Here) -> Option<Self>

Why row, a BDT entry, is not read by a node at here; None when it may be. BDT entries are device data, so a hostile or broken table must not turn the survey into a broadcast, a multicast or a send to this host’s other services.

pub fn check_address(address: SocketAddrV4, here: &Here) -> Option<Self>

check for an address without a mask, such as a survey’s seed.
