Struct CVStack 

pub struct CVStack { /* private fields */ }

Efficient chaining value stack for Blake3 hash computation as described in section 5.1.2 of the Blake3 paper.

Implementations

impl CVStack

pub fn new() -> Self

Create a new empty CV stack.

pub fn add_chunk_chaining_value( &mut self, new_cv: ChainingValue, is_last_chunk: bool, )

Add a new chunk chaining value to the stack.

Parameters

• new_cv: The chaining value of the chunk to add.
• is_last_chunk: Whether this is the last chunk in the input.

pub fn finalize(&mut self) -> [u8; 32]

Finalize the stack and compute the root hash.

This should only be called after all chunks have been added.

pub fn reset(&mut self)

Resets the CV stack.

pub fn is_empty(&self) -> bool

Check if the stack is empty.

pub fn total_chunks(&self) -> u64

Get the number of chunks processed so far.

Trait Implementations

impl Default for CVStack

fn default() -> Self

Returns the “default value” for a type.
