Struct Decoys 

pub struct Decoys {
    offsets: Vec<u64>,
    signer_index: u8,
    ring: Vec<[Point; 2]>,
}

Decoy data, as used for producing a CLSAG.

Fields

offsets: Vec<u64>

signer_index: u8

ring: Vec<[Point; 2]>

Implementations

impl Decoys

#[doc(hidden)] pub fn ct_eq(&self, other: &Decoys) -> Choice

This equality runs in constant-time if the decoys are the same length.

This is not a public function as it is not part of our API commitment.

pub fn new( offsets: Vec<u64>, signer_index: u8, ring: Vec<[Point; 2]>, ) -> Option<Decoys>

Create a new instance of decoy data.

offsets are the positions of each ring member within the Monero blockchain, offset from the prior member’s position (with the initial ring member offset from 0).

This function runs in time variable to the length of the ring and the validity of the arguments.

pub fn len(&self) -> usize

The length of the ring.

pub fn offsets(&self) -> &[u64]

The positions of the ring members within the Monero blockchain, as their offsets.

The list is formatted as the position of the first ring member, then the offset from each ring member to its prior.

pub fn positions(&self) -> Vec<u64>

The positions of the ring members within the Monero blockchain.

This function is runs in time variable to the length of the ring.

pub fn signer_index(&self) -> u8

The index of the signer within the ring.

pub fn ring(&self) -> &[[Point; 2]]

The ring.

pub fn signer_ring_members(&self) -> [Point; 2]

The [key, commitment] pair of the signer.

This function is runs in time variable to the length of the ring.

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

Write the Decoys.

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 serialize(&self) -> Vec<u8>

Serialize the Decoys to a Vec<u8>.

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: &mut impl Read) -> Result<Decoys, Error>

Read a set of Decoys.

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 Decoys

fn clone(&self) -> Decoys

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Decoys

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

This implementation of fmt reveals the ring but not the index of the signer.

impl Drop for Decoys

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for Decoys

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.
