Errors thrown by TreeNodes

Variants

InvalidDirection(usize)

At the moment the only supported dirs are 0, 1

NoDirection(NodeLabelOption<NodeLabel>)

No direction provided for the node. Second parameter is the label of the child attempted to be set – if there is one, otherwise it is None.

NoChildAtEpoch(u64usize)

The node didn’t have a child in the given epoch

ParentNextEpochInvalid(u64)

The next epoch of this node’s parent was invalid

HashUpdateOrderInconsistent

The hash of a parent was attempted to be updated, without setting the calling node as a child.

NonexistentAtEpoch(NodeLabelu64)

The node did not exist at epoch

NoStateAtEpoch(NodeLabelu64)

The state of a node did not exist at a given epoch

DigestDeserializationFailed(String)

Failed to deserialize a digest
