Enum Error 

pub enum Error<E: Error + Send + 'static> {
    NotImplemented,
    PoolExhausted,
    WouldBlock,
    AcquireTimeout,
    Pool(E),
}

Generalized error type used by any instrumented pool.

Variants

NotImplemented

Pool operation not supported.

PoolExhausted

No available resources were found in the pool.

WouldBlock

Call would block the thread, and non-blocking operation was requested.

AcquireTimeout

Resource acquisition took longer than the specified timeout.

Pool(E)

Pool implementation-specific error.

Trait Implementations

impl<E: Debug + Error + Send + 'static> Debug for Error<E>

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

Formats the value using the given formatter.

impl<E> Display for Error<E>

where E: Display + Error + Send + 'static,

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

Formats the value using the given formatter.

impl<E: Error + Send + 'static> Error for Error<E>

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.
