Verification errors for an anchor checked against a JSONL ledger.

Variants

Jsonl(JsonlError)

The ledger could not be opened, decoded, or scanned.

EmptyLedger

The ledger had no event rows to bind an anchor to.

Fields

path: PathBuf

Ledger path that was being scanned.

InternalAnchorBuild

The verifier produced fields that did not satisfy the anchor format.

Fields

path: PathBuf

Ledger path that was being scanned.

source: AnchorParseError

Anchor validation failure.

ChainBroken

The ledger hash chain itself is invalid.

Fields

path: PathBuf

Ledger path that was being verified.

line: usize

1-based JSONL line number.

reason: String

Human-readable chain failure.

Truncated

Current ledger is shorter than the anchored position.

Fields

path: PathBuf

Ledger path that was being verified.

db_count: u64

Current number of rows in the ledger.

anchor_event_count: u64

Event count required by the anchor.

MissingPosition

The anchor names a position that has no event hash, such as zero.

Fields

path: PathBuf

Ledger path that was being verified.

anchor_event_count: u64

Event count required by the anchor.

PositionHashMismatch

Recomputed hash at the anchored position did not match the anchor.

Fields

path: PathBuf

Ledger path that was being verified.

event_count: u64

Event count required by the anchor.

observed: String

Recomputed hash at event_count.

expected: String

Hash declared by the anchor.

Trait Implementations

impl Debug for AnchorVerifyError

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

Formats the value using the given formatter.

impl Display for AnchorVerifyError

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

Formats the value using the given formatter.

impl Error for AnchorVerifyError

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<JsonlError> for AnchorVerifyError

fn from(source: JsonlError) -> Self

Converts to this type from the input type.
