Enum ProofError 

pub enum ProofError {
    InvalidMerkleProof,
    MissingArtifactsDigest,
    ArtifactsDigestMismatch,
}

Available on crate feature unstable only.

An error returned by OCS proof verification.

Variants

InvalidMerkleProof

The Merkle proof did not authenticate the leaf at the given index against the proof’s claimed tree_root.

MissingArtifactsDigest

The checkpoint summary’s checkpoint_commitments did not contain a CheckpointArtifacts entry — the summary cannot be used to anchor an OCS proof.

ArtifactsDigestMismatch

The reconstructed CheckpointArtifactsDigest (computed from the proof’s tree_root) did not match the digest committed to by the summary’s CheckpointArtifacts commitment.

Trait Implementations

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 From<MerkleError> for ProofError

fn from(_: MerkleError) -> Self

Converts to this type from the input type.

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.
