Enum ComputationType 

#[non_exhaustive]
#[repr(u8)]
pub enum ComputationType {
    BiometricAuth = 1,
    FraudScore = 2,
    FedNowPayment = 3,
    SolanaAttestation = 4,
    HatsGovernance = 5,
    BitcoinUtxo = 6,

}

Domain separator values defined by the substrate specification.

A substrate minted for one computation type can NEVER be confused with a substrate minted for another, because the type byte is covered by the SHA3-256 signing message.

Values are an append-only enum — once assigned, a value cannot be reused or removed without breaking every historical signature that used the old meaning.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BiometricAuth = 1

FHE biometric authentication match.

FraudScore = 2

FHE fraud scoring result.

FedNowPayment = 3

FedNow payment attestation.

SolanaAttestation = 4

Solana transaction attestation.

HatsGovernance = 5

HATS governance proof.

BitcoinUtxo = 6

Bitcoin UTXO quantum-insurance attestation.

KycVerification = 7

ZK-KYC identity verification.

ShareComputation = 8

H33-Share cross-institution computation.

ArchiveSign = 9

ArchiveSign document attestation.

MedVaultPhi = 10

MedVault PHI operation.

VaultKeyOp = 11

VaultKey secret operation.

ApiResponse = 12

HTTP API response attestation (Tier 1 substrate response middleware).

GenericFhe = 255

Generic FHE computation — catch-all for unrelated uses.

Implementations

impl ComputationType

pub const fn from_byte(byte: u8) -> Option<Self>

Convert from a raw byte. Returns None for values the verifier does not recognize.

Examples

use h33_substrate_verifier::ComputationType;

assert_eq!(ComputationType::from_byte(0x01), Some(ComputationType::BiometricAuth));
assert_eq!(ComputationType::from_byte(0x0C), Some(ComputationType::ApiResponse));
assert_eq!(ComputationType::from_byte(0x42), None);

pub const fn to_byte(self) -> u8

Convert to the raw byte value.

Trait Implementations

impl Clone for ComputationType

fn clone(&self) -> ComputationType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComputationType

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

Formats the value using the given formatter.

impl Hash for ComputationType

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 PartialEq for ComputationType

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