Internal state of the canonical field codec.

Variants

Idle

Waiting for an encode/decode request.

Load

Load ten source limbs into the local work BRAM.

PairIssue

Issue reads for one adjacent carry pair.

PairCaptureCurrent

Capture the current work limb.

PairCaptureNext

Capture the following work limb.

PairWriteCurrent

Write the masked current limb.

PairWriteNext

Write the following limb with propagated carry.

QuotientIssue

Issue the most-significant limb used to decide canonical subtraction.

QuotientCapture

Capture and compute the canonicalization quotient.

AddModulusIssue

Issue the low limb before conditionally adding 19.

AddModulusWrite

Apply the quotient-derived modulus correction.

FinishIssue

Issue a final bounded limb read.

FinishCapture

Capture a final result limb.

Pack

Pack canonical limbs into bytes and compute flags.

Done

Present the codec result.

Trait Implementations

impl Clone for FieldCodecState

fn clone(&self) -> FieldCodecState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldCodecState

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

Formats the value using the given formatter.

impl Default for FieldCodecState

fn default() -> FieldCodecState

Returns the “default value” for a type.

impl Digital for FieldCodecState

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 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 dont_care() -> FieldCodecState

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 binary_string(self) -> String

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

impl PartialEq for FieldCodecState

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