Struct BufferedMerkleRootBuilder 

pub struct BufferedMerkleRootBuilder<T> { /* private fields */ }

Calculates the merkle root for a given set of data. The leaf hashes of the merkle tree can optionally be collected for use with a MerkleVerifier.

BufferedMerkleRootBuilder is able to accept data that isn’t a multiple of BLOCK_SIZE by internally buffering the data.

If all of the data is already in memory then MerkleRootBuilder::default().complete(data) should be used instead as it avoids buffering the tail end of the data if it’s not a complete block.

Implementations

impl<T: LeafHashCollector> BufferedMerkleRootBuilder<T>

pub fn new(leaf_hash_collector: T) -> Self

Creates a new BufferedMerkleRootBuilder with a LeafHashCollector.

Use BufferedMerkleRootBuilder::default() if a LeafHashCollector isn’t needed.

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

Appends data to the merkle tree.

pub fn complete(self) -> T::Output

Finishes building the merkle tree and returns the merkle root.

Trait Implementations

impl Default for BufferedMerkleRootBuilder<NoopLeafHashCollector>

fn default() -> Self

Returns the “default value” for a type.

impl<T: LeafHashCollector> Write for BufferedMerkleRootBuilder<T>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
