Struct IfaceAddr 

#[non_exhaustive]
pub struct IfaceAddr {
    pub cidr: IpCidr,
    pub origin: AddrOrigin,
    pub preferred_until: Option<Instant>,
}

An IP address assigned to an interface.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

cidr: IpCidr

The address and its prefix.

origin: AddrOrigin

Where the address came from.

preferred_until: Option<Instant>

When the address stops being preferred and becomes deprecated (RFC 4862 section 5.5.4). None means “forever”.

Only SLAAC sets this: a router advertises a preferred lifetime alongside the valid one, and shortens it to zero to signal that a prefix is on its way out while addresses formed from it still work.

Implementations

impl IfaceAddr

pub fn is_preferred(&self, now: Instant) -> bool

Whether the address is still preferred, i.e. not deprecated.

A deprecated address keeps working for connections that already use it, but is avoided when a source address is chosen for a new one.
