Enum HintStoreError 

pub enum HintStoreError {
    OverCapacity {
        max_bytes: u64,
    },
    ZeroTtl,
    EmptyPayload,
}

Errors produced by HintStore::enqueue.

Variants

OverCapacity

The store has reached max_bytes. The caller is expected to fall back to its non-handoff error path (typically, return DynomiteNoQuorumAchieved to the client) and the next drainer sweep will reclaim space when peers come back online.

Fields

max_bytes: u64

Configured upper bound, in bytes.

ZeroTtl

The supplied TTL is zero. A zero TTL would be expired immediately by the next sweep, so the store rejects it up front to surface a configuration error.

EmptyPayload

The hint payload is empty. The wire-replay path requires at least one byte; an empty payload is rejected so the drainer never produces a no-op outbound write.

Trait Implementations

impl Debug for HintStoreError

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

Formats the value using the given formatter.

impl Display for HintStoreError

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

Formats the value using the given formatter.

impl Error for HintStoreError

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 HintStoreError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
