Error variants related to configuration.

Since: 0.10.0: added quorum-loss inactivity validation error

Variants

ParseError

Failed to parse configuration from command-line arguments.

Since: 0.10.0: source from AnyError to BoxedErrorSource

Fields

source: BoxedErrorSource

The underlying parse error.

args: Vec<String>

The arguments that failed to parse.

ElectionTimeout

The min election timeout is not smaller than the max election timeout.

Fields

min: u64

Minimum election timeout value.

max: u64

Maximum election timeout value.

MaxPayloadIs0

The max_payload_entries configuration must be greater than 0.

ElectionTimeoutLTHeartBeat

Election timeout must be greater than heartbeat interval.

Fields

election_timeout_min: u64

Minimum election timeout value.

heartbeat_interval: u64

Heartbeat interval value.

HeartbeatMinIntervalTooLarge

Heartbeat suppression must not delay a heartbeat past a follower’s election timeout.

Since: 0.10.0

Fields

election_timeout_min: u64

Minimum election timeout value.

heartbeat_interval: u64

Heartbeat interval value.

heartbeat_min_interval: u64

Minimum interval between two heartbeats to the same follower.

QuorumLossProbeIntervalTooSmall

The probe interval must leave time for follower lease expiry and an election.

Since: 0.10.0: added quorum-loss inactivity validation

Fields

election_timeout_max: u64

Maximum election timeout in milliseconds.

probe_interval: u64

Configured heartbeat phase interval in milliseconds.

InvalidSnapshotPolicy

Invalid snapshot policy string format.

Fields

invalid: String

The invalid policy string provided.

syntax: String

The expected syntax format.

InvalidNumber

Failed to parse a number from string.

Fields

invalid: String

The invalid number string.

reason: String

The reason for the parse failure.

InvalidBackoff(ParseError)

Invalid backoff policy string.

See backoff_series::BackoffSeries::parse for the expected format.

Since: 0.10.0

Trait Implementations

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Eq for ConfigError

impl Error for ConfigError

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 From<ParseError> for ConfigError

fn from(source: BackoffParseError) -> Self

Converts to this type from the input type.

impl PartialEq for ConfigError

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for ConfigError
