Struct WatcherId 

pub struct WatcherId(/* private fields */);

An opaque long-lived handle identifying one watch subscriber.

Allocated by the backend’s owning thread; never interpreted by the channel logic. Backends should hand out monotonically increasing values from a per-loop counter.

Implementations

impl WatcherId

pub fn new(value: u64) -> Self

Construct a watcher id from a raw value.

The caller (the backend’s owning thread) is responsible for uniqueness within its loop.

pub fn as_u64(&self) -> u64

The raw identifier value.
