Struct Commitment 

pub struct Commitment<G: AffineRepr> {
    pub comm: G,
    pub shifted_comm: Option<G>,
}

Commitment to a polynomial that optionally enforces a degree bound.

Fields

comm: G

A Pedersen commitment to the polynomial.

shifted_comm: Option<G>

A Pedersen commitment to the shifted polynomial. This is none if the committed polynomial does not enforce a strict degree bound.

Trait Implementations

impl<G: AffineRepr> CanonicalDeserialize for Commitment<G>

fn deserialize_with_mode<R: Read>( reader: R, compress: Compress, validate: Validate, ) -> Result<Self, SerializationError>

The general deserialize method that takes in customization flags.

fn deserialize_compressed<R>(reader: R) -> Result<Self, SerializationError>

where R: Read,

Reads Self from reader using the compressed form if applicable. Performs validation if applicable.

fn deserialize_compressed_unchecked<R>( reader: R, ) -> Result<Self, SerializationError>

where R: Read,

Reads Self from reader using the compressed form if applicable, without validating the deserialized value.

fn deserialize_uncompressed<R>(reader: R) -> Result<Self, SerializationError>

where R: Read,

Reads Self from reader using the uncompressed form. Performs validation if applicable.

fn deserialize_uncompressed_unchecked<R>( reader: R, ) -> Result<Self, SerializationError>

where R: Read,

Reads Self from reader using the uncompressed form, without validating the deserialized value.

impl<G: AffineRepr> CanonicalSerialize for Commitment<G>

fn serialize_with_mode<W: Write>( &self, writer: W, compress: Compress, ) -> Result<(), SerializationError>

The general serialize method that takes in customization flags.

fn serialized_size(&self, compress: Compress) -> usize

Returns the size in bytes of the serialized version of self with the given compression mode.

fn serialize_compressed<W>(&self, writer: W) -> Result<(), SerializationError>

where W: Write,

Serializes self into writer using the compressed form if applicable.

fn compressed_size(&self) -> usize

Returns the size in bytes of the compressed serialized version of self.

fn serialize_uncompressed<W>(&self, writer: W) -> Result<(), SerializationError>

where W: Write,

Serializes self into writer using the uncompressed form.

fn uncompressed_size(&self) -> usize

Returns the size in bytes of the uncompressed serialized version of self.

impl<G: AffineRepr> Clone for Commitment<G>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<G: AffineRepr> Debug for Commitment<G>

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

Formats the value using the given formatter.

impl<G: AffineRepr> Default for Commitment<G>

fn default() -> Self

Returns the “default value” for a type.

impl<G: AffineRepr> Hash for Commitment<G>

fn hash<__HG>(&self, __state: &mut __HG)

where __HG: Hasher,

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<G: AffineRepr> PCCommitment for Commitment<G>

fn empty() -> Self

Outputs a non-hiding commitment to the zero polynomial.

fn has_degree_bound(&self) -> bool

Does this commitment have a degree bound?

impl<G: AffineRepr> PCPreparedCommitment<Commitment<G>> for PreparedCommitment<G>

fn prepare(vk: &Commitment<G>) -> Self

prepare PreparedCommitment from Commitment

impl<G: AffineRepr> PartialEq for Commitment<G>

fn eq(&self, other: &Self) -> 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<G: AffineRepr> Valid for Commitment<G>

const TRIVIAL_CHECK: bool

Whether the check method is trivial (i.e. always returns Ok(())). If this is true, the batch_check method will skip all checks and return Ok(()). This should be set to true for types where check is trivial, e.g. integers, field elements, etc. This is false by default. This is primarily an optimization to skip unnecessary checks in batch_check.

fn check(&self) -> Result<(), SerializationError>

Checks whether self is valid. If self is valid, returns Ok(()). Otherwise, returns an error describing the failure. This method is called by deserialize_with_mode if validate is Validate::Yes.

fn batch_check<'a>( batch: impl Iterator<Item = &'a Self> + Send, ) -> Result<(), SerializationError>

where Self: 'a,

Checks whether all items in batch are valid. If all items are valid, returns Ok(()). Otherwise, returns an error describing the first failure.
