Struct darkfi_sdk::crypto::smt::Path

source ·
pub struct Path<const N: usize, F: FieldElement, H: FieldHasher<F, 2>> {
    pub path: [F; N],
    hasher: H,
}
Expand description

The path contains a sequence of sibling nodes that make up a Merkle proof. Each sibling node is used to identify whether the merkle root construction is valid at the root.

Fields§

§path: [F; N]

Path from leaf to root. It is a list of sibling nodes. It does not contain the root node. Similar to other conventions here, the list starts higher in the tree and goes down. So when iterating we start from the end.

§hasher: H
