Struct MeasurementsTable 

pub struct MeasurementsTable { /* private fields */ }

Concurrent measurements table — one entry per name prefix, keyed by the longest-matching prefix used during the forwarding decision.

Updated on every Data arrival by the MeasurementsUpdateStage. Read by strategies via StrategyContext.

On native targets uses DashMap for sharded concurrent access. On wasm32 uses a Mutex<HashMap> (single-threaded WASM has no contention).

Implementations

impl MeasurementsTable

pub fn new() -> Self

Create an empty measurements table.

pub fn get(&self, name: &Arc<Name>) -> Option<MeasurementsEntry>

Look up the measurements entry for a name prefix, returning a clone.

pub fn update_rtt(&self, name: Arc<Name>, face: FaceId, rtt_ns: f64)

Record an RTT sample for a (prefix, face) pair, creating the entry if needed.

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

Snapshot all entries, returning a Vec of (prefix, entry) pairs.

Intended for management dataset queries (measurements/list).

pub fn update_satisfaction(&self, name: Arc<Name>, satisfied: bool)

Record an Interest satisfaction outcome, updating the EWMA satisfaction rate.

Trait Implementations

impl Default for MeasurementsTable

fn default() -> Self

Returns the “default value” for a type.
