Enum PoolError 

#[non_exhaustive]
pub enum PoolError {
    Exhausted(usize),
    Timeout(Duration),
    Creation(String),
    Reset(String),
    Closed,
}

Error type for pool operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Exhausted(usize)

Pool has reached maximum capacity and no sandboxes are available.

Timeout(Duration)

Timed out waiting for an available sandbox.

Creation(String)

Failed to create a new sandbox instance.

Reset(String)

Failed to reset sandbox state.

Closed

Pool has been shut down.

Trait Implementations

impl Debug for PoolError

Formats the value using the given formatter.

impl Display for PoolError

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

impl Error for PoolError

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<Error> for PoolError

fn from(err: Error) -> Self

Converts to this type from the input type.
