Enum AsyncPoolError 

pub enum AsyncPoolError {
    PoolShutdown,
    CircuitOpen,
    PoolExhausted,
    Timeout,
    LockPoisoned,
}

Pool-specific error conditions.

Variants

PoolShutdown

Pool is shutting down, no new connections allowed

CircuitOpen

Circuit breaker is open for the requested connection

PoolExhausted

All connections are busy or unhealthy

Timeout

Timed out waiting for a connection

LockPoisoned

Internal lock was poisoned

Trait Implementations

impl Clone for AsyncPoolError

fn clone(&self) -> AsyncPoolError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AsyncPoolError

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

Formats the value using the given formatter.

impl Display for AsyncPoolError

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

Formats the value using the given formatter.

impl Error for AsyncPoolError

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<AsyncPoolError> for VoltError

fn from(e: AsyncPoolError) -> Self

Converts to this type from the input type.

impl PartialEq for AsyncPoolError

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