Struct DeviceTable 

pub struct DeviceTable { /* private fields */ }

Thread-safe device discovery table.

Keyed by device instance number (the instance part of the DEVICE object identifier). Updated whenever an IAm is received.

Implementations

impl DeviceTable

pub fn new() -> Self

pub fn upsert(&mut self, device: DiscoveredDevice)

Insert or update a discovered device.

The table is capped at 4096 entries. If the table is full and the device is not already present, the new entry is silently dropped.

pub fn all(&self) -> Vec<DiscoveredDevice>

Get all discovered devices as a snapshot.

pub fn get(&self, instance: u32) -> Option<&DiscoveredDevice>

Look up a device by instance number.

pub fn get_by_mac(&self, mac: &[u8]) -> Option<&DiscoveredDevice>

Look up a device by its MAC address.

pub fn clear(&mut self)

Clear all entries.

pub fn len(&self) -> usize

Number of discovered devices.

pub fn is_empty(&self) -> bool

Whether the table is empty.

pub fn purge_stale(&mut self, max_age: Duration)

Remove entries whose last_seen is older than max_age.
