Enum HangingGetServerError

pub enum HangingGetServerError {
    MultipleObservers,
    NoBroker,
    RateLimit,
    Generic(Error),
}

Error types that may be used by the async hanging-get server.

Variants

MultipleObservers

An existing observer was already present for the client.

NoBroker

The HangingGetBroker associated with this handle has been dropped.

RateLimit

This handle is sending messages faster than the broker can process them.

Generic(Error)

Generic hanging-get server error.

Trait Implementations

impl Debug for HangingGetServerError

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

Formats the value using the given formatter.

impl Display for HangingGetServerError

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

Formats the value using the given formatter.

impl Error for HangingGetServerError

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 From<Canceled> for HangingGetServerError

fn from(e: Canceled) -> Self

Converts to this type from the input type.

impl From<Error> for HangingGetServerError

fn from(e: Error) -> Self

Try downcasting to more specific error types, falling back to Generic if that fails.

impl From<SendError> for HangingGetServerError

fn from(error: SendError) -> Self

Converts to this type from the input type.

impl PartialEq for HangingGetServerError

fn eq(&self, other: &Self) -> 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.
