Struct HostResolution 

#[non_exhaustive]
pub struct HostResolution {
    pub ips: Arc<NonEmptyVec<IpAddr>>,
    pub fetched_at: Instant,
    pub state: Extensions,
}

Available on crate feature dns only.

The data a DnsIpPicker sees for a single host

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.

ips: Arc<NonEmptyVec<IpAddr>>

Resolved IPs for the host. Guaranteed non-empty by construction (the cache only stores resolutions that produced at least one IP).

fetched_at: Instant

When the resolution was last fetched

state: Extensions

Per-host state

Pickers can stash their own state here, e.g. a round-robin cursor
