Struct secp256k1zkp::pedersen::Commitment

pub struct Commitment(pub [u8; 33]);

A Pedersen commitment

Methods

impl Commitment

pub fn as_ptr(&self) -> *const u8

Converts the object to a raw pointer for FFI interfacing

pub fn as_mut_ptr(&mut self) -> *mut u8

Converts the object to a mutable raw pointer for FFI interfacing

pub fn len(&self) -> usize

Returns the length of the object as an array

pub fn is_empty(&self) -> bool

Returns whether the object as an array is empty

impl Commitment

pub fn from_vec(v: Vec<u8>) -> Commitment

Builds a Hash from a byte vector. If the vector is too short, it will be completed by zeroes. If it's too long, it will be truncated.

pub fn to_pubkey(&self, secp: &Secp256k1) -> Result<PublicKey, Error>

Converts a commitment to a public key

Trait Implementations

impl AsRef<[u8]> for Commitment

fn as_ref(&self) -> &[u8]

impl Eq for Commitment

impl PartialEq<Commitment> for Commitment

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

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

This method tests for !=.

impl Clone for Commitment

fn clone(&self) -> Commitment

Returns a copy of the value.

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

Performs copy-assignment from source.
