Struct FactoryData 

pub struct FactoryData {
    pub window: [[b8; 64]; 2],
    pub pk_nonce: [b8; 16],
    pub older_nonces: [[b8; 16]; 1],
    pub result: [b32; 16],
    pub result_tag: b32,
}

Resetless datapath state.

Wide data registers without reset: reset logic on hundreds of bits costs area, and these values are only used when a matching valid flag in FactoryControl says so.

Fields

window: [[b8; 64]; 2]

Two-block XOF window, indexed by block parity.

window[0] holds the latest even block, window[1] the latest odd block, 64 bytes each.

pk_nonce: [b8; 16]

Current key’s pk_nonce for chain salting and the commitment prefix.

older_nonces: [[b8; 16]; 1]

The PACK_HISTORY keys before it, newest first.

Needed because chain ends of a key can emerge after newer keys have started feeding (see PACK_HISTORY).

result: [b32; 16]

Registered lane result.

Sixteen 32-bit words: the full BLAKE3 compression output.

result_tag: b32

Tag of the registered result.

Layout from lane_tag_kernel: kind in bits 0..4, argument in bits 4..9, context from bit 9, external tag in bits 16..32.

Trait Implementations

impl Clone for FactoryData

fn clone(&self) -> FactoryData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FactoryData

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

Formats the value using the given formatter.

impl Digital for FactoryData

const BITS: usize

Associated constant that gives the total number of bits needed to represent the value.

fn static_kind() -> Kind

Returns the [Kind] (run time type descriptor) of the value as a static method

fn bin(self) -> Box<[BitX]>

Returns the binary representation of the value as a vector of [BitX].

fn dont_care() -> Self

Returns a “don’t care” value for the type.

fn bits() -> usize

Returns the number of bits needed to represent the value.

fn kind(&self) -> Kind

Returns the [Kind] (run time type descriptor) of the value.

fn typed_bits(self) -> TypedBits

Returns the value as a [TypedBits], which includes both the bits and the kind.

fn discriminant(self) -> TypedBits

Returns the discriminant of the value as a [TypedBits].

fn variant_kind(self) -> Kind

Returns the [Kind] of the variant if the value is an enum with variants.

fn binary_string(self) -> String

Returns the binary representation of the value as a string of ‘0’, ‘1’, and ‘X’.

impl PartialEq for FactoryData

fn eq(&self, other: &FactoryData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
