Implementations

impl XfrAmount

pub fn is_confidential(&self) -> bool

Return true only if amount is confidential.

Example:

use noah_api::xfr::structs::XfrAmount;
use noah_algebra::ristretto::CompressedRistretto;
let xfr_amount = XfrAmount::Confidential((CompressedRistretto::default(), CompressedRistretto::default()));
assert!(xfr_amount.is_confidential());
let xfr_amount = XfrAmount::NonConfidential(100u64);
assert!(!xfr_amount.is_confidential());

pub fn get_amount(&self) -> Option<u64>

Return Some(amount) if amount is non-confidential. Otherwise, return None

Example:

use noah_api::xfr::structs::XfrAmount;
use noah_algebra::ristretto::CompressedRistretto;
let xfr_amount = XfrAmount::NonConfidential(100u64);
assert_eq!(xfr_amount.get_amount().unwrap(), 100u64);
let xfr_amount = XfrAmount::Confidential((CompressedRistretto::default(), CompressedRistretto::default()));
assert!(xfr_amount.get_amount().is_none());

pub fn get_commitments(
    &self
) -> Option<(CompressedRistretto, CompressedRistretto)>

Return Some((c1,c2)), where (c1,c2) is a commitment to the amount if amount is confidential. Otherwise, return None

Example:

use noah_api::xfr::structs::XfrAmount;
use noah_algebra::ristretto::CompressedRistretto;
let xfr_amount = XfrAmount::NonConfidential(100u64);
assert!(xfr_amount.get_commitments().is_none());
let xfr_amount = XfrAmount::Confidential((CompressedRistretto::default(), CompressedRistretto::default()));
assert_eq!(xfr_amount.get_commitments().unwrap(), (CompressedRistretto::default(), CompressedRistretto::default()));

pub fn from_blinds(
    pc_gens: &PedersenCommitmentRistretto,
    amount: u64,
    blind_lo: &RistrettoScalar,
    blind_hi: &RistrettoScalar
) -> Self

Construct a confidential amount with an amount and an amount blind.

Trait Implementations

impl Clone for XfrAmount

fn clone(&self) -> XfrAmount

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for XfrAmount

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for XfrAmount

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<XfrAmount> for XfrAmount

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
