}

Errors that can occur when validating SMT proofs.

Variants

InvalidMerklePathLength(usize)

The length of the provided Merkle path is not SMT_DEPTH.

InvalidKeyForProof

The key maps to a different leaf index than the proof’s leaf.

ValueMismatch

The value does not match the value in the leaf for the given key.

Fields

expected: Word

actual: Word

ConflictingRoots

The computed root does not match the expected root.

Fields

expected_root: Word

actual_root: Word

ValuePresent

The key-value pair exists in the tree.

Fields

key: Word

value: Word

Trait Implementations

impl Debug for SmtProofError

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

Formats the value using the given formatter.

impl Display for SmtProofError

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

Formats the value using the given formatter.

impl Error for SmtProofError

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 SmtProofError

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