}

Error happening when a provided DFS path does not exist within a known part of a tree.

Variants

PathNotExists(DfsPath)

the provided DFS path {0} does not exist within a given tree.

HiddenNode

Fields

node_hash: TapNodeHash

The hash of the hidden node found during the path traversal.

failed_path: DfsPath

The path segment which leads to the hidden node.

path_leftover: DfsPath

The path segment which was not able to traverse after the hidden node.

the provided DFS path traverses hidden node {node_hash} at {failed_path} to {path_leftover}.

LeafNode

Fields

leaf_script: LeafScript

The hash of the leaf script of a leaf node found during the path traversal.

failed_path: DfsPath

The path segment which leads to the leaf node.

path_leftover: DfsPath

The path segment which was not able to traverse after the leaf node.

the provided DFS path traverses leaf node {leaf_script} at {failed_path} to {path_leftover}.
