Struct MerkleTree 

Source 
pub struct MerkleTree { /* private fields */ }
Expand description

A Merkle tree for efficient content verification.

The tree is built from leaf nodes (content chunks) and allows generating proofs that a specific chunk is part of the content.

Implementations§

§Arguments
  • leaf_index - Index of the leaf to generate proof for
§Returns

A Merkle proof that can be used to verify the leaf.

Source
