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

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

impl PixSpec for HoprPixSpec

Available on crate feature pix-bjj and non-crate feature pix-secp256k1 only.

const HASH_TO_SCALAR_SUITE_ID: &'static [u8] = b"BabyJubJub_XMD:BLAKE3_SSWU_RO_"

Stable, protocol-versioned hash-to-scalar suite identifier used for domain separation. This must be a fixed string — deriving it dynamically from Debug output would break wire compatibility when dependency versions change formatting.

const PIX_SUITE: PixSuite = hopr_protocol_pix::PixSuite::BabyJubJub

Which curve this spec instantiates, as announced to the peer in PixParams.

type AddressPrivateKey = BjjKeypair

Private key type.

type Cipher = StreamCipherCoreWrapper<ChaChaCore<R20, Ietf>>

Stream cipher used to encrypt the SSA shares.

type Curve = BabyJubJub

Prime order elliptic curve use for commitments.

type DepositAddress = BjjPublicKey

Deposit address type.

type Digest = Hasher

Digest used for hashing operations.

type Pseudonym = SimplePseudonym

Pseudonym used to identify groups of SURBs.

fn group_to_deposit_address( group: <<HoprPixSpec as PixSpec>::Curve as CurveArithmetic>::ProjectivePoint, ) -> Option<<HoprPixSpec as PixSpec>::DepositAddress>

Converts PixGroup to an address that can be deposited to.

fn scalar_to_private_key( scalar: <<HoprPixSpec as PixSpec>::Curve as CurveArithmetic>::Scalar, ) -> Option<<HoprPixSpec as PixSpec>::AddressPrivateKey>

Convert PixScalar to a private key of a deposit address.

const KEY_DERIVATION_CONTEXT: &'static str = "HASH_SSA_POLY_SHARE"

Context data used to derive the SSA encryption key.

const HASH_SCALAR_DERIVATION_CONTEXT: &'static str = "HASH_SSA_POLY_SHARE_SCALAR"

Domain separator used to derive the X value of a share.

const HASH_COMMITMENT_PROOF_CONTEXT: &'static str = "HASH_SSA_COMMITMENT_PROOF"

Domain separator used to derive the Fiat–Shamir challenge of an SsaCommitmentProof.

fn msg_to_scalar( spi: &SsaPolynomialId<Self::Pseudonym>, msg: impl AsRef<[u8]>, ) -> Result<<Self::Curve as CurveArithmetic>::Scalar, PixError<Self::Pseudonym>>

where Self: Sized,

Performs conversion of the given spi and msg into PixScalar of this spec.

fn commitment_proof_challenge( ssa_id: &SsaId<Self::Pseudonym>, ssa_commitment: &<Self::Curve as CurveArithmetic>::ProjectivePoint, nonce_commitment: &<Self::Curve as CurveArithmetic>::ProjectivePoint, ) -> Result<<Self::Curve as CurveArithmetic>::Scalar, PixError<Self::Pseudonym>>

where Self: Sized,

Derives the Fiat–Shamir challenge of an SsaCommitmentProof over the client’s ssa_commitment and the prover’s nonce_commitment.

impl Serialize for HoprPixSpec

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
