Struct MerkleTreeBuilder

pub struct MerkleTreeBuilder { /* private fields */ }

A MerkleTreeBuilder generates a MerkleTree from one or more write calls.

Examples

let data = vec![0xff; 8192];
let mut builder = MerkleTreeBuilder::new();
for i in 0..8 {
    builder.write(&data[..]);
}
assert_eq!(
    builder.finish().root(),
    "f75f59a944d2433bc6830ec243bfefa457704d2aed12f30539cd4f18bf1d62cf"
        .parse()
        .unwrap()
);

Implementations

impl MerkleTreeBuilder

pub fn new() -> Self

Creates a new, empty MerkleTreeBuilder.

pub fn write(&mut self, buf: &[u8])

Append a buffer of bytes to the merkle tree.

No internal buffering is required if all writes are BLOCK_SIZE aligned.

pub fn push_data_hash(&mut self, hash: Hash)

Save a data block hash, propagating full blocks of hashes to higher layers. Also clear a stored data block.

pub fn finish(self) -> MerkleTree

Finalize all levels of the merkle tree, converting this MerkleTreeBuilder instance to a MerkleTree.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MerkleTreeBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MerkleTreeBuilder

fn default() -> Self
