Typed rejection of presence evidence.

Variants

Stale

Evidence predates the retained participant version.

Fields

participant: K

Participant.

observed: PresenceVersion

Rejected version.

current: PresenceVersion

Current version.

lifetime: Duration

Exact rejected lifetime.

ConflictingVersion

Evidence reuses a version with a different lifetime or phase.

Fields

participant: K

Participant.

version: PresenceVersion

Reused version.

lifetime: Duration

Exact rejected lifetime.

TimerCollision

A currently present different participant owns the mapped timer key.

Fields

participant: K

Rejected participant.

existing: K

Existing participant owning the timer key.

timer_id: TimerId

Colliding timer key.

version: PresenceVersion

Exact rejected evidence version.

lifetime: Duration

Exact rejected lifetime.

GenerationExhausted

No fresh timer generation is representable.

Fields

participant: K

Participant whose refresh was rejected.

version: PresenceVersion

Exact rejected evidence version.

lifetime: Duration

Exact rejected lifetime.

Trait Implementations

impl<K: Clone> Clone for PresenceError<K>

fn clone(&self) -> PresenceError<K>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for PresenceError<K>

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

Formats the value using the given formatter.

impl<K> Display for PresenceError<K>

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

Formats the value using the given formatter.

impl<K> Error for PresenceError<K>

where Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<K: PartialEq> PartialEq for PresenceError<K>

fn eq(&self, other: &PresenceError<K>) -> 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.
