Struct BlockHasher

pub struct BlockHasher { /* private fields */ }

Incremental hasher for a single block, this can only be used to hash only one block.

Implementations

impl BlockHasher

pub fn new() -> Self

Create a new block hasher using the default IV

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

pub fn update_rayon(&mut self, input: &[u8])

pub fn update_with_join<J: Join>(&mut self, input: &[u8])

pub fn set_block(&mut self, block: usize)

Set the index of the block which we’re hashing with this BlockHasher.

Panics

This function can only be called right after instantiating a BlockHasher, this will panic if it gets called after any bytes were consume by the hasher.

pub fn len(&self) -> usize

Returns the number of bytes this block hasher has been fed so far.

pub fn finalize(self, is_root: bool) -> [u8; 32]

Returns the final output from the block hasher, if the file is only composed of one block, set is_root to true to get the finalized hash and not the chaining value.

Trait Implementations

impl Clone for BlockHasher

fn clone(&self) -> BlockHasher

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<IV> for BlockHasher

fn from(value: IV) -> Self

Converts to this type from the input type.
