Enum KvCacheEventError 

#[non_exhaustive]
pub enum KvCacheEventError {
    ParentBlockNotFound,
    BlockNotFound,
    InvalidBlockSequence,
    CapacityExhausted,
    AllocationFailed,
    OwnershipDegreeOverflow,
    IndexerInvariantViolation,
}

Errors that can occur during KV Cache Event processing.

Indexer backends may introduce additional failure modes. Downstream matches must include a wildcard arm because this enum is non-exhaustive.

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.

ParentBlockNotFound

BlockNotFound

InvalidBlockSequence

CapacityExhausted

A bounded, pre-commit index omission; this does not prove the backing table is full.

AllocationFailed

A pre-commit allocation or reservation failed; no lossy-capacity policy is implied.

OwnershipDegreeOverflow

An exact ownership degree overflowed before mutation.

IndexerInvariantViolation

impl Eq for KvCacheEventError

impl Error for KvCacheEventError

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.

impl PartialEq for KvCacheEventError

fn eq(&self, other: &KvCacheEventError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
