Struct Commitment 

pub struct Commitment {
    pub hash: [u8; 32],
}

A commitment: hash of (randomness || value).

Fields

hash: [u8; 32]

32-byte SHA-256 hash.

Implementations

impl Commitment

pub fn create(value: &[u8]) -> (Self, Decommitment)

Create a commitment to value with fresh randomness. Returns (commitment, decommitment).

pub fn create_with_randomness( value: &[u8], randomness: [u8; 32], ) -> (Self, Decommitment)

Create a commitment with explicit randomness (for testing or deterministic protocols).

pub fn verify(&self, decommitment: &Decommitment) -> bool

Verify a decommitment against this commitment.

pub fn to_hex(&self) -> String

Serialize commitment hash as hex.

pub fn from_hex(hex_str: &str) -> Result<Self, String>

Deserialize from hex.

Trait Implementations

impl Clone for Commitment

fn clone(&self) -> Commitment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Commitment

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Commitment

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Commitment

impl Hash for Commitment

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 Commitment

fn eq(&self, other: &Commitment) -> 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 Commitment

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
