Enum MerkleTreeError

pub enum MerkleTreeError {
    WrongBatchSize,
    WrongWidth,
    WrongHeight {
        log_max_height: usize,
        num_siblings: usize,
    },
    IncompatibleHeights,
    IndexOutOfBounds {
        max_height: usize,
        index: usize,
    },
    RootMismatch,
    EmptyBatch,
}

Errors that may arise during Merkle tree commitment, opening, or verification.

Variants

WrongBatchSize

The number of openings provided does not match the expected number.

WrongWidth

A matrix has a different width than expected.

WrongHeight

The number of proof nodes does not match the expected tree height.

Fields

log_max_height: usize

Expected log2 of the maximum matrix height.

num_siblings: usize

Actual number of sibling hashes provided in the proof.

IncompatibleHeights

Matrix heights are incompatible; they cannot share a common binary Merkle tree.

IndexOutOfBounds

The queried row index exceeds the maximum height.

Fields

max_height: usize

Maximum admissible height.

index: usize

Row index that was provided.

RootMismatch

The computed Merkle root does not match the provided commitment.

EmptyBatch

Attempted to open an empty batch (no committed matrices).

Trait Implementations

impl Debug for MerkleTreeError

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

Formats the value using the given formatter.

impl Display for MerkleTreeError

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

Formats the value using the given formatter.

impl Error for MerkleTreeError

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.
