Reject reasons surfaced by ReplicationConfig::validate.

Not Eq — the Self::BudgetFractionOutOfRange variant carries an f32, which is PartialEq but not Eq.

Variants

FactorBelowMin

factor is below the REPLICATION_FACTOR_MIN floor.

Fields

got: u8

Configured factor value.

min: u8

Minimum permitted factor.

FactorAboveMax

factor is above the REPLICATION_FACTOR_MAX ceiling.

Fields

got: u8

Configured factor value.

max: u8

Maximum permitted factor.

HeartbeatTooLow

heartbeat_ms is below the HEARTBEAT_MS_MIN floor.

Fields

got: u64

Configured heartbeat cadence.

min: u64

Minimum permitted heartbeat cadence.

HeartbeatTooHigh

heartbeat_ms is above the HEARTBEAT_MS_MAX ceiling. Pathological values let heartbeat_ms.saturating_mul(miss_threshold) saturate to u64::MAX, silently disabling silence detection.

Fields

got: u64

Configured heartbeat cadence.

max: u64

Maximum permitted heartbeat cadence.

BudgetFractionOutOfRange

replication_budget_fraction is outside (0.0, 1.0] or non-finite (NaN / ±inf).

Fields

got: f32

Configured budget fraction.

BackgroundFractionOutOfRange

background_fraction is outside [0.0, 1.0) or non-finite. 1.0 is rejected because it would deny every Background request unconditionally.

Fields

got: f32

Configured background fraction.

PinnedSetEmpty

PlacementStrategy::Pinned supplied an empty Vec<NodeId>. Pinned placement needs at least one node; if the operator wanted “no replication” they should leave RedexFileConfig::replication at None instead.

PinnedSetTooLarge

PlacementStrategy::Pinned supplied more than REPLICATION_FACTOR_MAX nodes.

Fields

got: usize

Number of nodes in the pinned set.

max: usize

Maximum permitted pinned-set size.

PinnedDuplicate

A NodeId appears more than once in the pinned set.

Fields

node_id: NodeId

The duplicated NodeId.

LeaderPinnedOutsidePinnedSet

leader_pinned names a node that isn’t in the pinned set — the operator pinned a leader on a node that won’t even run a replica.

Fields

leader: NodeId

The leader NodeId that lies outside the pinned set.

Trait Implementations

impl Debug for ReplicationConfigError

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

Formats the value using the given formatter.

impl Display for ReplicationConfigError

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

Formats the value using the given formatter.

impl Error for ReplicationConfigError

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 ReplicationConfigError

fn eq(&self, other: &ReplicationConfigError) -> 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.
