Struct fuchsia_merkle::MerkleTreeBuilder
source · pub struct MerkleTreeBuilder { /* private fields */ }
Expand description
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§
source§impl MerkleTreeBuilder
impl MerkleTreeBuilder
sourcepub fn write(&mut self, buf: &[u8])
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.
sourcepub fn push_data_hash(&mut self, hash: Hash)
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.
sourcepub fn finish(self) -> MerkleTree
pub fn finish(self) -> MerkleTree
Finalize all levels of the merkle tree, converting this MerkleTreeBuilder
instance to a
MerkleTree
.
