Enum scylla::transport::errors::ConnectionPoolError

#[non_exhaustive]
pub enum ConnectionPoolError {
    Broken {
        last_connection_error: ConnectionError,
    },
    Initializing,
    NodeDisabledByHostFilter,
}

An error that occurred when selecting a node connection to perform a request on.

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.

Broken

A connection pool is broken. Includes an error of a last connection.

Fields

last_connection_error: ConnectionError

Initializing

A connection pool is still being initialized.

NodeDisabledByHostFilter

A corresponding node was disabled by a host filter.

Trait Implementations

impl Clone for ConnectionPoolError

fn clone(&self) -> ConnectionPoolError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionPoolError

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

Formats the value using the given formatter.

impl Display for ConnectionPoolError

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

impl Error for ConnectionPoolError

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

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
