Struct CompressionInput 

pub struct CompressionInput {
    pub cv: [b32; 8],
    pub block: [b32; 16],
    pub counter_low: b32,
    pub counter_high: b32,
    pub block_len: b32,
    pub flags: b32,
    pub tag: b32,
    pub valid: bool,
}

One compression request; all fields except valid are ignored in bubbles.

Everything compress takes, as RHDL bit vectors, plus a tag and a valid bit. 8 + 16 + 5 words of 32 bits and one bit of valid.

Fields

cv: [b32; 8]

Original chaining value, or IV/key words for a first block.

block: [b32; 16]

Zero-padded message block decoded as little-endian words.

counter_low: b32

Low 32 bits of the chunk counter, or root XOF output-block counter.

counter_high: b32

High 32 bits of the chunk counter, or root XOF output-block counter.

block_len: b32

Number of meaningful bytes in the input block, in 0..=64.

flags: b32

Caller-supplied BLAKE3 compression flags.

tag: b32

Opaque caller tag, preserved without interpretation.

valid: bool

Marks a real input token; false inserts a pipeline bubble.

Implementations

impl CompressionInput

Host-side helpers for building requests in tests and models.

pub fn new( cv: [u32; 8], block: [u32; 16], counter: u64, block_len: u32, flags: u32, tag: u32, ) -> Self

Encodes a valid request from ordinary Rust integer words.

The 64-bit counter is split into counter_low and counter_high.

pub fn salted_16( pk_hash: [u8; 32], nonce: [u8; 16], message: [u8; 16], tag: u32, ) -> Self

Prepares a valid fixed-size salted-message request.

The same request salted_input_kernel builds in hardware.

Trait Implementations

impl Clone for CompressionInput

fn clone(&self) -> CompressionInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionInput

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

Formats the value using the given formatter.

impl Default for CompressionInput

fn default() -> CompressionInput

Returns the “default value” for a type.

impl Digital for CompressionInput

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 CompressionInput

fn eq(&self, other: &CompressionInput) -> 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.
