A chain-verification failure from verify_log.

Variants

IdMismatch

A record’s stored op_id doesn’t match its content.

Fields

op_id: String

DeviceMismatch

hlc.device_id disagrees with the record’s device_id.

Fields

op_id: String

DuplicateSeq

Two ops from one device claim the same seq.

Fields

device_id: String

seq: u64

SeqGap

A device’s seqs aren’t contiguous from its first present op.

Fields

device_id: String

expected: u64

found: u64

PrevMismatch

prev doesn’t link to the device’s preceding op (or seq 0 has one).

Fields

op_id: String

NonMonotonicHlc

A device’s HLC stamps aren’t strictly increasing along its chain.

Fields

op_id: String

TruncatedChain

DeviceLog::resume was handed a log in which the resuming device’s own chain doesn’t start at seq 0 — a truncated tail. Resuming from it would re-mint truncated seqs (a permanent chain fork); go through checkpoint::resume_anchored instead.

Fields

device_id: String

first_seq: u64

Trait Implementations

impl Clone for ChainError

fn clone(&self) -> ChainError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChainError

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

Formats the value using the given formatter.

impl Display for ChainError

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

Formats the value using the given formatter.

impl Eq for ChainError

impl Error for ChainError

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<ChainError> for SessionError

fn from(e: ChainError) -> Self

Converts to this type from the input type.

impl PartialEq for ChainError

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