Enum CircuitHashType 

pub enum CircuitHashType {
    DefaultRustHash,
    Sha3_256,
    Poseidon,
}

Defines the type of hash used when adding a circuit description’s hash into the transcript.

Variants

DefaultRustHash

This uses Rust’s std::collections::hash_map::DefaultHasher implementation and uses the #[derive(Hash)] implementation. The hash function implemented underneath is not cryptographically secure, and thus this option is generally not recommended.

Sha3_256

This converts the circuit description into a JSON string via serde::Serialize and hashes the bytes using SHA3-256.

Poseidon

This converts the circuit description into a JSON string via serde::Serialize and hashes the bytes in chunks of 16, converting them first to field elements.

Trait Implementations

impl Clone for CircuitHashType

fn clone(&self) -> CircuitHashType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CircuitHashType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CircuitHashType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CircuitHashType

fn eq(&self, other: &CircuitHashType) -> 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 Serialize for CircuitHashType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for CircuitHashType
