Implementations

impl EncodableWitness

pub const fn new( id: usize, constraint: Option<usize>, value: Scalar, source: EncodableSource, ) -> Self

Create a new encodable witness instance

pub const fn id(&self) -> usize

Id of the witness in the constraint system

pub const fn constraint(&self) -> Option<usize>

Constraint that originated the witness

pub const fn value(&self) -> &Scalar

Value of the witness in the constraint system

pub const fn source(&self) -> &EncodableSource

Source reference to be encoded

Trait Implementations

impl Clone for EncodableWitness

fn clone(&self) -> EncodableWitness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncodableWitness

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

Formats the value using the given formatter.

impl Default for EncodableWitness

fn default() -> EncodableWitness

Returns the “default value” for a type.

impl Element for EncodableWitness

fn len(ctx: &Config) -> usize

Serializable length

fn validate(&self, preamble: &Preamble) -> Result<()>

Perform the internal validations of the associated element

fn validate_buffer(config: &Config, buffer: &[u8]) -> Result<()>

Assert the buffer is big enough to store the type

impl EncodableElement for EncodableWitness

fn to_buffer(&self, ctx: &mut EncoderContext, buf: &mut [u8])

Write the type into the buffer.

fn to_vec(&self, ctx: &mut EncoderContext) -> Vec<u8>

Serialize the object into a bytes array.

fn encode<'a>( &self, ctx: &mut EncoderContext, buf: &'a mut [u8], ) -> &'a mut [u8]

Read an element into the buffer, returning the remainder bytes

fn try_to_writer<W>(&self, writer: W, ctx: &mut EncoderContext) -> Result<usize>

where W: Write,

Send the bytes representation of an element to a writer

impl Hash for EncodableWitness

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for EncodableWitness

fn cmp(&self, other: &EncodableWitness) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EncodableWitness

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

impl PartialOrd for EncodableWitness

fn partial_cmp(&self, other: &EncodableWitness) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
