Errors from ChainManager::append_signed (WEFT-105 / K6.4 replay).

Variants

AlreadyPresent

Event with this sequence and hash is already on the local chain.

Fields

sequence: u64

Fork

Same sequence, different hash — DAG tip conflict (ADR-089).

Fields

sequence: u64

local_hash: [u8; 32]

remote_hash: [u8; 32]

Gap

Remote event skips ahead of the next expected sequence.

Fields

expected: u64

got: u64

ReservedSource

The event’s source is reserved for locally appended events.

Fields

event_source: String

ChainIdMismatch

Chain ID mismatch between local and remote event.

Fields

local: u32

remote: u32

PrevHashMismatch

prev_hash does not link to the local tip.

Fields

expected: [u8; 32]

got: [u8; 32]

PayloadHashMismatch

Stored payload_hash does not match a recomputation of the payload.

Fields

sequence: u64

HashMismatch

Stored event hash does not match a recomputation of the commitment.

Fields

sequence: u64

recomputed: [u8; 32]

stored: [u8; 32]

Trait Implementations

impl Clone for AppendSignedError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppendSignedError

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

Formats the value using the given formatter.

impl Display for AppendSignedError

impl Eq for AppendSignedError

impl Error for AppendSignedError

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 AppendSignedError

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

Equality operator ==.

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

Inequality operator !=.
