Enum ClusterStateTokenError

#[non_exhaustive]
pub enum ClusterStateTokenError {
    TokenCalculation(TokenCalculationError),
    Serialization(SerializationError),
    UnknownTable {
        keyspace: String,
        table: String,
    },
}

Error returned from ClusterState APIs.

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.

TokenCalculation(TokenCalculationError)

Failed to calculate token.

Serialization(SerializationError)

Failed to serialize values required to compute partition key.

UnknownTable

ClusterState doesn’t currently have metadata for the requested table.

Fields

keyspace: String

table: String

Trait Implementations

impl Clone for ClusterStateTokenError

fn clone(&self) -> ClusterStateTokenError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClusterStateTokenError

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

Formats the value using the given formatter.

impl Display for ClusterStateTokenError

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

Formats the value using the given formatter.

impl Error for ClusterStateTokenError

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.
