Struct diem_sdk::crypto::hash::TransactionAccumulatorHasher

pub struct TransactionAccumulatorHasher(_);

The hasher used to compute the hash of an internal node in the transaction accumulator.

Trait Implementations

impl Clone for TransactionAccumulatorHasher

fn clone(&self) -> TransactionAccumulatorHasher

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CryptoHasher for TransactionAccumulatorHasher

fn seed() -> &'static [u8; 32]

the seed used to initialize hashing Self before the serialization bytes of the actual value

fn update(&mut self, bytes: &[u8])

Write bytes into the hasher.

fn finish(self) -> HashValue

Finish constructing the HashValue.

fn hash_all(bytes: &[u8]) -> HashValue

Convenience method to compute the hash of a complete byte slice.

impl Debug for TransactionAccumulatorHasher

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

Formats the value using the given formatter.

impl Default for TransactionAccumulatorHasher

fn default() -> TransactionAccumulatorHasher

Returns the “default value” for a type.

impl Write for TransactionAccumulatorHasher

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

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

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

Flush 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, fmt: Arguments<'_>) -> Result<(), Error>

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

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

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