Enum scylla::transport::errors::ConnectionError

#[non_exhaustive]
pub enum ConnectionError {
    ConnectTimeout,
    IoError(Arc<Error>),
    NoSourcePortForShard(u32),
    TranslationError(TranslationError),
    BrokenConnection(BrokenConnectionError),
    ConnectionSetupRequestError(ConnectionSetupRequestError),
}

An error that appeared on a connection level. It indicated that connection can no longer be used and should be dropped.

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.

ConnectTimeout

Provided connect timeout elapsed.

IoError(Arc<Error>)

Input/Output error occurred.

NoSourcePortForShard(u32)

Driver was unable to find a free source port for given shard.

TranslationError(TranslationError)

Failed to translate an address before establishing a connection.

BrokenConnection(BrokenConnectionError)

A connection has been broken after being established.

ConnectionSetupRequestError(ConnectionSetupRequestError)

A request required to initialize a connection failed.

Implementations

impl ConnectionError

pub fn is_address_unavailable_for_use(&self) -> bool

Checks if this error indicates that a chosen source port/address cannot be bound. This is caused by one of the following:

• The source address is already used by another socket,
• The source address is reserved and the process does not have sufficient privileges to use it.

Trait Implementations

impl Clone for ConnectionError

fn clone(&self) -> ConnectionError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionError

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

Formats the value using the given formatter.

impl Display for ConnectionError

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

Formats the value using the given formatter.

impl Error for ConnectionError

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

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.
