Struct Blake2bCircuit 

pub struct Blake2bCircuit {
    pub length: usize,
    pub message: Vec<Wire>,
    pub digest: [Wire; 8],
}

BLAKE2b circuit following single-block pattern Processes messages block-by-block like Blake2s

Fields

length: usize

Message size in bytes this circuit supports

message: Vec<Wire>

Witness wires for the input message (little-endian 64-bit words)

digest: [Wire; 8]

Witness wires for the expected 512-bit digest (8 × 64-bit words)

Implementations

impl Blake2bCircuit

pub fn new(builder: &CircuitBuilder) -> Self

Create a new BLAKE2b circuit with standard 64-byte output

pub fn new_with_length( builder: &CircuitBuilder, max_msg_len_bytes: usize, ) -> Self

Create a new BLAKE2b circuit for messages up to max_msg_len_bytes

pub fn new_with_params( builder: &CircuitBuilder, max_msg_len_bytes: usize, outlen: usize, ) -> Self

Create a new BLAKE2b circuit with specified message length and output length

pub fn populate_message(&self, w: &mut WitnessFiller<'_>, message: &[u8])

Populate the message data into the witness

pub fn populate_digest(&self, w: &mut WitnessFiller<'_>, digest: &[u8; 64])

Populate the expected digest output for verification
