Defines errors which can occur when using Merkle trees.

Variants

TooFewLeaves(usize, usize)

Fewer than two leaves were used to construct a Merkle tree.

NumberOfLeavesNotPowerOfTwo(usize)

Number of leaves for a Merkle tree was not a power of two.

LeafIndexOutOfBounds(usize, usize)

A leaf index was greater than or equal to the number of leaves in the tree.

DuplicateLeafIndex

A leaf index was included more than once in the list of indexes for a batch proof.

TooFewLeafIndexes

No leaf indexes were provided for a batch Merkle proof.

TooManyLeafIndexes(usize, usize)

Too many leaf index were provided for a batch Merkle proof.

InvalidProof

Merkle proof is not valid for the specified position(s).

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MerkleTreeError

fn eq(&self, other: &MerkleTreeError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
