Struct Words512 

pub struct Words512 {
    pub words: [b64; 8],
}

A 512-bit value represented as little-endian 64-bit words.

Holds either a 64-byte message or a 64-byte R || S signature.

Fields

words: [b64; 8]

Little-endian words; word zero carries bits 63 through 0.

Implementations

impl Words512

Host-side conversions between byte arrays and Words512, plus a zero constructor for reset values.

pub fn from_le_bytes(bytes: [u8; 64]) -> Self

Pack a host byte array without hashing or changing the message.

Byte 8 * i + j becomes byte j of word i, so the packed value is the array read as one little-endian 512-bit integer.

This adapter is for drivers and testbenches, not a hardware kernel.

use rhdl_ed25519_scalable_core::Words512;
let message = [0x42; 64];
assert_eq!(Words512::from_le_bytes(message).to_le_bytes(), message);

pub fn to_le_bytes(self) -> [u8; 64]

Unpack a message or signature returned by the hardware boundary.

Inverse of Self::from_le_bytes; for a signature the result is the 64-byte RFC 8032 R || S encoding.

pub fn zero() -> Self

Construct zero.

Used for register reset values and idle pipeline stages.

Trait Implementations

impl Clone for Words512

fn clone(&self) -> Words512

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Words512

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

Formats the value using the given formatter.

impl Digital for Words512

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 Words512

fn eq(&self, other: &Words512) -> 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.
