Struct Commitment 

pub struct Commitment {
    pub mask: Scalar,
    pub amount: u64,
}

The opening for a Pedersen commitment commiting to a u64.

Fields

mask: Scalar

The mask for this commitment.

amount: u64

The amount committed to by this commitment.

Implementations

impl Commitment

#[doc(hidden)] pub fn zero() -> Commitment

A commitment to 0, defined with a mask of 1 (as to not be the identity).

This follows the Monero protocol’s definition for a commitment without randomness. https://github.com/monero-project/monero /blob/ac02af92867590ca80b2779a7bbeafa99ff94dcb/src/ringct/rctOps.cpp#L333

pub fn new(mask: Scalar, amount: u64) -> Commitment

Create a new Commitment.

pub fn commit(&self) -> Point

Commit to the value within this opening.

pub fn write<W: Write>(&self, w: &mut W) -> Result<()>

Write the Commitment.

This is not a Monero protocol defined struct, and this is accordingly not a Monero protocol defined serialization. This may run in time variable to its value.

pub fn read<R: Read>(r: &mut R) -> Result<Commitment>

Read a Commitment.

This is not a Monero protocol defined struct, and this is accordingly not a Monero protocol defined serialization. This may run in time variable to its value.

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 ConstantTimeEq for Commitment

fn ct_eq(&self, other: &Self) -> Choice

Determine if two items are equal.

fn ct_ne(&self, other: &Self) -> Choice

Determine if two items are NOT equal.

impl Debug for Commitment

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

This implementation reveals the Commitment’s amount.

impl Drop for Commitment

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for Commitment

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
