Struct FabricDns 

pub struct FabricDns { /* private fields */ }

Fabric DNS resolver for mapping node names to socket addresses.

Provides name registration and lookup with TTL-based cache expiry. Names follow the <node_id>.fabric or <human_name>.fabric convention.

This is an in-memory implementation suitable for testing and single-process use. A production implementation would query the fabricBIOS control plane.

Example

use grafos_net::FabricDns;
use std::net::SocketAddr;
use std::time::Duration;

let mut dns = FabricDns::new(Duration::from_secs(300));
let addr: SocketAddr = "10.10.0.11:5701".parse().unwrap();
dns.register("node-b.fabric", addr);

let resolved = dns.resolve("node-b.fabric").unwrap();
assert_eq!(resolved, vec![addr]);

Implementations

impl FabricDns

pub fn new(ttl: Duration) -> Self

Create a new DNS resolver with the given TTL for cached entries.

pub fn register(&mut self, name: &str, addr: SocketAddr)

Register a name-to-address mapping.

If the name already exists, the entry is replaced with a fresh TTL.

pub fn resolve(&self, name: &str) -> Option<Vec<SocketAddr>>

Resolve a fabric node name to its registered addresses.

Returns None if the name is not registered or has expired.

pub fn evict_expired(&mut self)

Remove expired entries from the cache.
