Enum HashRingError

pub enum HashRingError {
    InvalidConfiguration(u8, Vnid),
    VirtualNodeAlreadyExists(String),
    VirtualNodeDoesNotExist(String),
    ConcurrentModification,
    EmptyRing,
    SingleDistinctNodeRing,
}

An error type returned by calls to the API exposed by this crate.

Variants

InvalidConfiguration(u8, Vnid)

The configuration parameters for the construction of the consistent hashing ring appears to be invalid.

The error contains the invalid values for the replication factor and the number of virtual nodes per ring node, in this order.

VirtualNodeAlreadyExists(String)

A hash collision has been detected; one of the virtual nodes probably already exists in the consistent hashing ring.

VirtualNodeDoesNotExist(String)

One of the virtual nodes does not exist in the consistent hashing ring.

ConcurrentModification

The write operation on the consistent hashing ring failed due to some other write operation occurring concurrently on it.

EmptyRing

The consistent hashing ring is currently empty.

SingleDistinctNodeRing

Only one Node currently populates the consistent hashing ring.

Trait Implementations

impl Debug for HashRingError

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

Formats the value using the given formatter.

impl Display for HashRingError

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

Formats the value using the given formatter.

impl Error for HashRingError

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.
