Enum ProofError

}

Errors from proof verification.

Variants

OriginMismatch

Origin hash doesn’t match the log.

HashMismatch

Hash at a given sequence doesn’t match.

Fields

seq: u64

Sequence number where mismatch occurred.

expected: u64

Expected hash from the proof.

got: u64

Actual hash from the local log.

MissingEvent(u64)

Event at the given sequence is missing from the local log.

InvalidRange

Proof has from_seq > to_seq — reversed bounds.

Fields

from_seq: u64

Lower bound declared by the proof.

to_seq: u64

Upper bound declared by the proof.

SpanTooLarge

Proof span exceeds MAX_PROOF_VERIFY_SPAN — to_seq - from_seq is too large to walk safely.

Fields

from_seq: u64

Lower bound declared by the proof.

to_seq: u64

Upper bound declared by the proof.

cap: u64

Configured maximum span the verifier will walk.

Trait Implementations

impl Clone for ProofError

fn clone(&self) -> ProofError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProofError

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

Formats the value using the given formatter.

impl Display for ProofError

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

Formats the value using the given formatter.

impl Error for ProofError

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 ProofError

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