Enum WatchMode 

pub enum WatchMode {
    Events,
    Polling,
    CacheOnly,
}

How property updates will be delivered after calling watch()

This enum indicates the mechanism that will be used to receive property updates. The SDK automatically selects the best available method.

Variants

Events

UPnP event subscription is active - real-time updates will be received

This is the preferred mode, providing immediate notifications when properties change on the device.

Polling

UPnP subscription failed, updates may come via polling fallback

The event manager was configured but subscription failed (possibly due to firewall). The SDK’s polling fallback may still provide updates, but they won’t be real-time.

CacheOnly

No event manager configured - cache-only mode

Properties will only update when explicitly fetched via fetch(). Call system.configure_events() to enable automatic updates.

Trait Implementations

impl Clone for WatchMode

fn clone(&self) -> WatchMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WatchMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for WatchMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for WatchMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WatchMode

fn eq(&self, other: &WatchMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
