Struct Fib 

pub struct Fib { /* private fields */ }

The Forwarding Information Base.

A name trie mapping prefixes to FibEntry values. Concurrent longest-prefix match with per-node RwLock (via NameTrie).

Implementations

impl Fib

pub fn new() -> Self

pub fn lpm(&self, name: &Name) -> Option<Arc<FibEntry>>

Longest-prefix match lookup.

pub fn add_nexthop(&self, prefix: &Name, face_id: FaceId, cost: u32)

Register a nexthop for prefix. Replaces any existing entry.

pub fn dump(&self) -> Vec<(Name, Arc<FibEntry>)>

Return all FIB entries as (prefix_uri, [(face_id, cost)]) tuples.

pub fn remove_prefix(&self, prefix: &Name)

Remove the entry for prefix entirely, regardless of nexthops.

pub fn set_nexthops(&self, prefix: &Name, nexthops: Vec<FibNexthop>)

Atomically replace all nexthops for prefix.

Used by the RIB to apply computed nexthops. If nexthops is empty the entry is removed.

pub fn remove_face(&self, face_id: FaceId)

Remove all nexthops pointing to face_id across all prefixes.

Called when a face is closed to prevent stale routes from accumulating.

pub fn remove_nexthop(&self, prefix: &Name, face_id: FaceId)

Remove the nexthop for face_id from prefix.

Trait Implementations

impl Default for Fib

fn default() -> Self

Returns the “default value” for a type.
