Enum KeyspaceStrategyError

#[non_exhaustive]
pub enum KeyspaceStrategyError {
    MissingClassForStrategyDefinition,
    MissingReplicationFactorForSimpleStrategy,
    ReplicationFactorParseError(ParseIntError),
    UnexpectedNetworkTopologyStrategyOption {
        key: String,
        value: String,
    },
}

An error that occurred during specific keyspace’s metadata fetch.

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.

MissingClassForStrategyDefinition

Keyspace strategy map missing a class field.

MissingReplicationFactorForSimpleStrategy

Missing replication factor for SimpleStrategy.

ReplicationFactorParseError(ParseIntError)

Replication factor could not be parsed as unsigned integer.

UnexpectedNetworkTopologyStrategyOption

Received an unexpected NTS option. Driver expects only ‘class’ and replication factor per dc (‘dc’: rf)

Fields

key: String

value: String

Trait Implementations

impl Clone for KeyspaceStrategyError

fn clone(&self) -> KeyspaceStrategyError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyspaceStrategyError

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

Formats the value using the given formatter.

impl Display for KeyspaceStrategyError

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

Formats the value using the given formatter.

impl Error for KeyspaceStrategyError

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.
