Struct Enumerator 

pub struct Enumerator { /* private fields */ }

Stateful device enumerator: holds the per-device probe cache so the polling watcher reuses immutable data across ticks instead of re-handshaking every device every ~2s. One-shot callers use the enumerate free function, which runs against a fresh (empty) cache.

Implementations

impl Enumerator

pub async fn enumerate( &mut self, ) -> Result<Vec<DeviceInventory>, InventoryError>

One enumeration pass, reusing the cache from prior passes. Probes every HID candidate concurrently (so one asleep node that burns the whole PROBE_BUDGET can’t stall the others), reusing each device’s cached immutable data when it’s present and fresh.

A node the OS still lists but whose probe fails (receiver registers unanswered, probe timeout, open failure) is not reported as absent: its last completed inventory is replayed for a bounded grace and its channel is reopened, so a transient HID++ glitch can’t masquerade as “no devices” (#218) — see the node ledger.

Trait Implementations

impl Default for Enumerator

fn default() -> Enumerator

Returns the “default value” for a type.
